The T2 stage is lacking, and it's a big part of our ladder games, so i think it's legit to buff their ACU for the T2-T3 phase to make this stage less painfull. Both upgrade ideas are nice, original and not just "buff rhino stats".
But in general : i think it's cool to have a general patern of cybra/aeon having weak t2 but strong t1/t3 and uef/sera having the big t2 push. I understand the will to polish the rough angles, but if we go too hoverboard in that direction, it makes gameplay a little less exciting, since all faction will play pretty much the same. I like the idea of "you have weak t2, just don't play too much into it, and tech into your strenghts" just like aeon used to have useless t2 so you would ignore this phase and rush t3. It bring games where you see big t2 army vs few t3 units rather than "big ball of t2 fights similar ball of t2".
Don't be so negative about your faction ! 
Despite all the weak points, cybran still have a few godlike things you can play around ...
- Superior T1 tank
- Superior frigate and annoying stealthed units
- Superior T3 air with very annoying stealth
- Great T3 land units despite the lack of shields and snipers (but try to use snipers against a stealthed brick/treb army ... )
You can't say "cybran have nothing to put on the board".
