Asylum - Makes sense, it's T2 and can hover.
Titan/Loyalist - This will play out strangely, the Loyalist probably more negatively impacted. If you can't crank out as many as quickly, why not a brick?
Sniper bots - I feel like this is too much too fast, I can see some of the changes being reversed, likely the mass cost, the build time is good.
Ahwassa - With the energy increase, I'm not sure the AoE shrink is needed. The additional infrastructure needed to afford the power requirements seems like a big hit.
Czar - I'm not sure how this will play out.
Valiant - I like it, UEF units tend to have more HP. It'll be the Pillar of Destroyers, if that makes sense. Not great DPS, high HP, sticks around for a long time to "Tar pit" the enemy.
Salem - It seems like such a small change, not sure what will happen.
Sparky - I like the idea of stealth fields and radar, I don't like T1 factory ability.
Kennel/drone - solid change.
Nukes - Seems fair, once someone has one, if they're dug in hard enough it's hard to stop them.
Nuke Subs - Good, follows suit.
Loyalist and Billy nukes - I suppose this is fair, the idea of a Loyalist tossing a billy back is funny though.
UEF T3 air jamming - Make it cost as much as Cybran stealth for it's Energy cost.
With cybran and UEF having stealth and jamming, what of Aeon and Seraphim? I suggest increasing the Omni radius of the Aeon T3 spy plane, and adding that temporary vision to the Seraphim T3 spy planes, maybe a bigger vision radius after it crashes.
