The T3 MAA becoming cheaper and more spammable + HP normalization is good. Flak all have the same HP, which is good, although T1 MAA have slightly different HP (And Aeon has the lowest, not Cybran). I guess air gets so much more important the longer the game goes on its only fair for every faction to have identical HP on their land AA.
The T2 air changes are mostly lip curling. Nerfing T2 transport speed again? Making the Stinger even weaker and more spammable so it's even worse against flak? Making the Vulthoo even denser so it's better against flak? Nerfing the Janus spamability? Making ASF even more resistant to ground AA?
Air HQ timing coming online a bit later is whatever. Although that combined with the UEF air nerfs seems punishing for air UEF players.
Teleport being worthless (aside from Billy memes, the teleport upgrade is now worthless on ACUS) is so lame. When you take the E cost into account, Telemaser can be countered quite cost-effectively with multiple shield layering and T2 PD. The Cybran ACU just continues to be homogenized with increased vision nerfing stealth, getting nano-regen, and now this.
For SACUs, now Aeons can't tele sacrifice GC. Seraphim can't tele OC. Seems like it just makes the late game less dynamic and volatile.
