Doesn't matter the cause. You've always been able to repair base buildings and I don't see a good reason for why it needed to be removed.
That good reason would be a new alternative win condition. Make annihilation victory actually a possibility because let's be real here, in 9 years of CoH2 NOBODY has ever won a VP game through annihilation against an opponent who was not complete or 2000+ ranks below you or a cpu.
Regardless of how it was in past CoH titles, doesn't it feel kinda weird standing in front of the burning wreckage of your HEADQUARTERS and being like "I want another chance! It's not fair that I lose!"
