I take back anything tha I have said previosly.
New thought:
I hate it. For aliens to win all they must do is have 2 rts and just not get a two hive lockdown. Nothing else. In the process get chambers. That's it. Not that hard. For rines, they must do everything correctly. I mean everything. Keep alien res down, keep theirs up, keep base alive, work together (hard concept even on LM), tech and TWO hive lockdown must be had or you lose. Sure it happens once in a blue moon...but it's not fun to play. At least in B5 you had some chance to come back. In this version, it seems that the game gets decided at a point, which is evident clearly while in game and it's a long slow death from there. It's not fun dominating so much and neither is it fun to be dominated all the time.
That said, I do like the changes which have been made, but not the way the whole balance has gotten skewed. Perhaps making fades/onos more expensive would be a solution. Maybe even just un-nerfing seiges. Just my two cents.
