As it is now, the human aspect will drive this game to the ground. Look at the early AM numbers which is symbolic of what happens when players have a choice.
I have seen players on the tail end getting hoarded to the point they can either log or join the horde. The numbers will never balance themselves out creating a crazy toxic environment.
Personally, if I have time during the early mornings, I have fun fighting the horde and love the imbalanced #s. Folks that play this game religiously do get frustrated and I don't blame them.
AI can be used to balance things out. I dont see any issue with it and am a bit confused because it is already part of the game with auto acks and factory AAA. Why not use it for other uses? I can understand getting shot down by a bot would be kind of lame, I think there are some good scenarios we can implement it.
