I have had the same experience as Jinsuko and klepp0906 when it comes to getting kicked for botting (so far have not been banned). Common complaints when I'm paired with the same people include:
1) running off to the same markers each game in the same order, especially when the team is elsewhere
2) fighting 10 vs 1 due to #1
3) chasing an enemy forever

I think a possible fix for tank/dps bots would be the following algorithm (perhaps added as Frontline mode):
1) ensure stay within X range of healer (randomly chosen if multiple healers, default to party leader if no healer)
2) iff #1 true, fight anything that comes within X range of healer, else return to healer / step 1

Potential problem with this algorithm (assuming it's possible to code it) I see are:
1) enemy ranged DPS attacking you from outside the X range of healer. I think to solve this making X larger than DPS attack range may help
2) the healer you are following is a bot... not sure how to fix this one. perhaps set it so you can't be healer in frontlines (which seems fair, I think healer is the most obvious class when it is being botted)

Not perfect, I think however it's still a big step up from current state behavior.
