Besides the lag I've noticed that you can't kick people from matches (what's the point of having the ability to kick them if you can't), and that AIs never repair turrets.
I can only speak for the offlline game mode,but I thought that I saw it happen once,but the more I think of it,I don't think I've ever seen it happen.
I guess that further illustrates that there needs to be some sort of command abilities to suggest to your AI teammates on what to do and where to go.
Or just make the bots smarter.
