I think that you need to be extremely careful when comparing SC2 and FAF (in context I am right now Number. 3 on FAF ladder and in Platinum league in SC2 after couple weeks of playing), while it's true that if an UI mod for SC2 exist that does what an UI mod for FAF does then it would absolutely busted and banned for sure (eg. a Disperse move for marines to avoid Banelings to kill them with their AOE) because it removes a vital part of SC2 which is unit micro. The same can be said for an UI mod that would control economy in FAF where it would automatically add pgens, pauses everything that uses power (E-please or whatever it was called mod). That's because a lot of FAF depth lies in economy and macro, much more then in SC2 (in SC2 unless you are Zerg (Queen injects) the economy is basically Select all Nexus/CC/Hatchery make drones while having the hatchery's waypoint on mineral line/Gas).
Now back to the topic, I believe that UI mods like ATP (Advanced Target Priority), UI party, Spread move, Disperse move actually increase the micro potential because of the importance and trade of's of Micro vs Micro.
Note: While in theory assuming perfect gameplay and APM of >300 on normal and probably >500 on big maps this wouldn't be true but we are mere mortals and taking into account that I am top 5 player It's safe to assume that If I can't do this and it's not optimal for me to invest my APM into it then it's not gonna be possible nor actually beneficial for other players.
I will try to now explain why I think that is and give a couple of examples. First of all we need to consider what these mods actually do, most of them allow us, the player, to better tell the units what we want them to do via orders or improve the way we give/queue the orders. ATP allows us to specify what we want the unit to target, Disperse move allows us to split the units more efficiently, same for UI party. As Archsimcat already stated you still do the same amount of work in game by giving orders, the part that is improved/simplified is the UI. Instead of needing to somehow (different methods for that as stated by Arch) select 5 groups i can select one, give the orders and tell them via a UI mod to just split. You may say that this is bad and takeaways the micro aspect of the game, but my point is that it doesn't, it allows you to better "translate" your actions to units and because of that micro more.
Why is that you may ask? Because if I am not allow to use that option then I won't do it at all, I just won't micro it (Excluding some edge cases like splitting very important units that you give a lot of APM attention like engies early game when there is nothing going on, your first 3 t3 units, your T4's etc.) and neither should you because it's just not worth it. Why would I spend 3 seconds on splitting my t1 tanks so that your bomber has 100 less mass killed value if this would mean that I am inefficient with my Mass/E/BP balance causing me to make 5 tanks less? Because of the importance and focus on economy most of the time it's just not worth it to invest a lot of attention nor APM into extensive unit micro in this game, It's just how it is.
Let's go over a few examples:
Example N.1 Mod in question - Disperse Move
As stated above a situation is as follows, a t1 bomber attacking my t1 tanks. If I would have disperse move option there is a chance I might quickly select my 4 tanks, give them 3-4 move orders around them and use my keybind for Disperse move. Take probably around 1-1.5 seconds. If I wouldn't have Disperse move I wouldn't bother to move my tanks at all, if I would have tried I could probably manage to move 1 away but realistically speaking, ask yourself, do you really see it out side of edge cases like first 2-3 minutes and special units? No you don't, I don't do it, I don't see it because it's too much hassle for little gain and it's more important to queue 1 more pgen so I don't power stall in 2 minutes.
Example N.2 Mod in question - ATP (Advanced Target Priority)
I have a few units doing a run by and I want to kill enemy mexes. I select my units and using ATP I use my keybind to tell them to focus mexes and move them in between mexes. I then have to options depending on the game state, I can either micro the units by giving move orders to avoid enemy units, dodge shots etc. to get maximum value out of them or leave them be if that's not really important. Now the same situation without ATP, I select my units and either just move them in and pray, move in and then queue Attack orders on mexes or just queue attack orders on mexes from the start. It takes a little bit more (given low amount of targets, don't kid yourself you don't need to queue more then 2-4 usually) time and "micro" to do so then using ATP BUT it doesn't at all allow for any future micro, I won't move micro my units cause they will move but stop shooting the mexes so I just queue and forget.
Another thing is a more strategic aspect like deciding that I want to prioritize targeting of t1 arties given the game state and both mine and enemy unit composition. Without ATP it wouldn't be possible and this takes a potential strategic and micro aspect of the game.
Over all the argument is that these mods don't take away micro from the game because Yes, they simplify some part of micro but if it's not simplified it's not used (except some edge cases where the mod isn't actually taking away the skill needed cause given low amount of orders value gained from the mod is so small it can be ignored) so nothing is lost, we actually gain the possibilities for micro and increase the potential of it. I would hate to see banning or blocking via changes such UI mods since it would make the game dumber, more boring and actually decrease both the focus on micro and it's potential.
Another thing I would like the bring up is balance, if the mod follows the basic rules (as stated by Mach) and it's not a cheat mod then it really doesn't make units OP (Few exceptions like Shift G + ATP on ACU priority). Did t2 arty/unit drops became OP after ATP? Yes they can be stronger bcs of ATP but it requires extra attention and micro (in order to get more value you need to set targeting to eg. power and then MICRO your arties so that they don't die to defences and stay at the edge of their range). T1 bombers doing Spread attack? Yes they will utilize their AOE more efficiently but it takes more clicks then just move + A-move or just A-Move.
All these mods do is take an aspect of micro that is in theory possible but not worth it because of the time required to achieve it being long due to UI being bad or UI limitations and making such move a viable one.
Back to Keyser.
"the pr you are showing is here to preventing cheating : UI mods abusing the feature to give order to units (ie auto dodging, auto hover bombing etc etc)" Agree with that, these are and should be considered cheat mods and therefore be banned."
"It is also here to remove the split move to trap ACU with T1 units (balance decision in accordance with the balance councillor)." I think this is a very weak argument for removing such an excellent feature like split move, I also don't see why unit blocking of ACU is so bad while for example while blocking an ACU with spamming of t1 aa is not (absolutely busted since it fucks with pathfinding insanely). I really fail to see how units getting on top of the ACU and blocking it is such a bad thing, yes it may be frustrating but I think it's healthy. ACU's are absolutely busted compared to units and you want to keep your ACU in range of enemy units while keeping your units outside of enemy's ACU range. If you move in your units on top of enemy ACU you should be able to block him at the cost of clumping up your units and making them more prone to OC. After all it's only effective if you have a lot more of units bcs of how attacking vs defending unit formation works. If blocking wouldn't be possible it would make ACU even stronger (bad idea in my opinion) and even if you have 50% more t1 tanks you still wouldn't be able to kill enemy with an all in because of defenders advantage in engagements and Vet on ACU etc.
" Spread move / disperse move not working after that, would be an unfortunate side effect." I think that there should be a focus on finding alternative solution if that's the case, it would be a huge loss for micro and gameplay to lose those mods.
Please make sure that your posts contains some actual information, don't make ridiculous claims like "oh this will make bombers OP" without giving it a second thought nor actually argumenting your position. You can have your own opinion but sharing it as facts is just foolish. This thread as all others derail and become a spam fiesta of people arguing and quoting each other back and forward for no real result. This stubborn guy won't change his mind about XYZ so just don't bother. This is not the place for that. Without deeper game knowledge or game balance you shouldn't really claim anything, you can hint that you think or in your opinion something is ... but it's really not that useful for the discussion. It may seem "elitist" but in 99% of the cases it's just the truth, if you don't understand the game well enough you can't say what's OP or UP cause most of the time you can't properly use it or counter it.
Footnote: I've spent a lot of time on this post and thought it through so I won't respond to some low effort quotation and BS claim by some random guy, so just don't bother. I am looking forward to get some answers from other top rated players, but mostly Balance and Game Dev Team as well as to use it in the near future in any related discussions so I won't need to spend 1h again explaining and argumenting my points.
