They work awesomely in lots of maps, although they have a tendency to entirely go Engineer at the slightest indication of losing...
Well, they can't handle payload, and they can't determine when a door will open for them.
I've yet to see a scout or spy bot.
The medic bots are pretty dumb. They only follow others around, they don't think for themselfes unless attacked while retreating. They also ignore people calling for medic.
Also, they all change classes on about half of their deaths. I've played offblast with four heavies and it was fun. They're best at KOTH and Arena.
