Hmmmm, I think it is supposed to go like this (in that this is how gpg intended)
Uef- super build speed, can make insta-fire base
Cybran- can handle itself in every sircumstance, doesn't excel in anything in particular, great for getting those lonely mass spots mid games etc.
Sera - I think this was supposed to be the best SACU with the insta ras and great dmg and oC upgrade ( I think this was there answer to exp defense since the chicken often does more harm than good)
Aeon - made to be the king of kiting, and a helpful unit.
How I feel they should be now:
Uef: insane builder, incapable of fighting exps, but can defend against them with great t3 pd spam
Cybran: good all rounder, should have great aa and decent damage. I feel like this should have a much more powerful death nuke, this way it could act like a sucide, like a 3.5 fire beetle
Sera: most expensive, ras built in. Basically you have to buy ras, unavoidable, but on the other side you can have ras and 3 other upgrades, bal would be necessary. OC should cost more, but I dot think it needs a huge nerf, I mean, it's useless without micro an doesn't work against acus and doesnt d full damage against buildings. as for tac, increase height, so it can't fly threw shields, but that's all
Aeon: oh boy, this ones a doosy... But I'll give it a go. I think it should be an anti-Percival/Brick, as aeon gets run over if they can't get GC up fast enough or if enough percivals or bricks pile up before the GC can finish the job. I think a huge damage- low fire rate unit would make sense, with enough range and sped to kite a Percy (assuming the map has the room) but not enough life to survive gunships, bombers, exps, kinda like a 3.5 aurora.
As for everything I feel like all the sACUs should cost more, not be nerfed to h-e- double hockey sticks
Thx for reading all the way through
