looks like someone already made that comment https://forum.faforever.com/topic/1027/the-scu-rebalance/29
if an issue is that the current RAS sACU is a multirole unit for ecoing, fighting, and building,
It is a preset for an upgrade. There is a base unit with combat, construction, and resource stats that can be upgraded.
If one reduces the stats of the base unit the other upgrades can be indirectly reduced.
To upgrade costs resources and APM for factions where multiple upgrades are possible. No mention of explosion radius and damage, speed, immobilization, veterancy, or other qualities. The sACUs (and gateway) remain a part of the game. If there weren't already an sACU rebalance coming I'd volunteer a mod (https://forum.faforever.com/topic/759/balance-thread-guidelines, https://forum.faforever.com/topic/739/guide-creating-a-basic-balance-mod-with-a-merge-blueprint, and for example https://github.com/FAForever/fa/commit/39032bf2c83a9024901db3784f0a6c1aecef2465)

Cybran t1 bots (LAB vs Mantis) do have the same icon and similar speeds at time of writing (4 vs 3.7) https://faforever.github.io/spooky-db/#/URL0106,URL0107
However they are distinguishable from how nimble they are (turn rate of 45 vs 80), the sounds they make when firing, projectile effect, and fire rate.
For those reasons I have not been confused by LABs and Mantis. To answer the question "is there any reason to keep it the same", because the LAB and Mantis are both bots and that is why they get the bot strategic icon.
Here is a drawing of a 5x5 map I stopped working on. The two ramps that approach each other get close enough to allow a factory to be distance built.
As a 10x10 I'm still deciding if the default player spawns should have cliffs instead of beaches to prevent hover units from being too overpowered. Perhaps small ramps to allow single units since that's also another path for an ACU to travel (to take the opposing expansion).
The circle dots are adaptive mexes that spawn with a second player. The reclaim is rocks nearby all the cliffs, trees around the map, and the civilian town in the middle.
