My feedback.
Sparky: T2 Field Engineer
Nice! Feels much better as a front line supporter. A bit worried the T1 factory blueprint part might be abusable but haven't had those fears confirmed yet.
Ambassador: T3 Strategic Bomber
Feels too strong now.
SR90 Blackbird: T3 Spy Plane
Like how it is unique now.
Loyalist: T3 Siege Assault Bot
The charge ability feels much better now with the change. Weapons staying active really helped make the ability feel worth the APM.
No more redirect on billy nuke was blatant UEF favouritism. Cruiser TDM can stop it, ergo loyalist TMD should to. Alternative: redirected billy nukes become viewed as hostile to TMD on return flight and can be shot down.
Usha-Ah: T3 Sniper Bot & Sprite Striker: T3 Sniper Bot
Nerfed again? They feel like mistakes to even build in the first place now. T3 direct fire unit balls now feel unstoppable by Sniper Bots.
T2 Air Transports
Crash damage increase was nice. Didn't know how much I wanted this change until it was thrust upon me.
Beacon Class: T1 Frigate
Feels too strong now. Perhaps revert build costs but keep range increase.
Bulwark: T2 Shield Boat
New change feels good. More relevant in T2 phase.
Hives & Kennels
Hives feel too costly for what you get.
Kennels feel better now as in-base consolidated BP. Rebuild cost on drones however makes them easy to abuse as fast flying engineers going around the map.
T2 Point Defense
Cerberus - Small buff. You needed it.
Oblivion - Small nerf. Still the worst. Missed an opportunity here to give it some love. More AOE?
Uttaushala - Small nerf.
Triad - Very small nerf. Did it need to get relatively (albeit slightly) stronger compared to the others?
All changes not commented on are either good changes or I don't have any particular thoughts about if they are good or bad changes yet.
