Honestly I've never understood the amazing amount of salt that comes out on both sides of the debate around using shift-G to more easily kill an ACU with T1 spam (and for that matter UI modding in general). Compared to now, comblocking required/will again require as little as 2-3 more clicks and being more zoomed in (move order past ACU, box-select first 1-3 tanks that pass ACU, move them to just in front of ACU). This is nearly as effective as shift-G with less risk of brutal overcharges. Maybe it's my out-of-date-1500 game knowledge, but I think people looking forward to being able to take significantly more risks with their ACUs in average and high level play might be in for a rude shock, especially as people are now more aware of the value of comblocking than in 2015. I think I'd prefer it stayed, if cheaters might be/are abusing it then get rid of it.
As a general point, I agree with having a UI that lets you more easily issue the orders you want to and to make more decisions for yourself directly through UI flexibility (UI Party's selection-splitting hotkeys are AMAZING for this, including just about replacing everything lost by removing shift-G) and indirectly through more thinking time. Having this approach seems to be a pretty fundamental design decision for Supcom both before and after FAF started, so it arguably damages the market appeal of FAF to go in the opposite direction. Scaling back UI control should only be done if something is absolutely ruining high level play, or clearly driving players away and endangering the community. I can't think of an example of the latter and I will just take the word of actual good players on things like ATP sniping being completely broken (actual balance decisions shouldn't be made by anyone else as they are, by definition, the people who best understand how to play the game optimally, sorry if that hurts people's feelings). I would quietly suggest that if people are concerned about lowering the FAF skill cap, they should read Tagada's post and then look at the skill cap as a unit/map balance issue. Given this game is meant to be about strategic choice based on all available info, not high-APM mechanics and managing a perma-zoomed in screen, we should be looking at making more unit comps and playstyles viable in various scenarios. If there are more meaningful strategic choices, not just a battle of execution in producing more of the "correct comp" than your opponent and/or taking better fights with it, good strategic players can shine. But again, I'm not good enough at this game to know if the skill cap is a real issue or better balanced units and maps are actually a good solution.
Also sidenote for @Tagada: Take your own advice on comparing FAF and Starcraft when you've only being playing SC2 for a couple of weeks and you're nowhere near the equivalent of even 1k FAF rating (Platinum players are ranked behind 30%-50%/70k-120k of active non-Korean ladder profiles, on FAF leaderboards that is currently 213-456 rating). You would be laughed out of town on any SC2 forum where you tried to argue that "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" - that's like saying FAF macro is basically shift-clicking mass points with a couple of engineers. Stick to FAF, you make a lot more sense when you do
