If this isn't enough to think there are bots in frontlines (mainly in shatter) I don't know what else is. And this was a while ago but at the time of this thread, its probably more appropriate, and sorry I know this is a not so active thread right now since 4.1 but there hasn't been a change, just had a 3 or 4/8 of the party of bots recently and it angered me.
