Granted, some of the players do things a lot dumber than bots, but let's stay on topic.
The worst experiences I've had so far involve the bot doing a 180 degree spin and finishing off the enemy whom you have worked so hard to kill. The bot then proceeds to step in front of your detpack, blocking it and causing your balls to explode as you inhale your own smoke screen that the enemy utilizes to throw a mine on in the midst of your confusion.
The idiot bot then proceeds to sprint directly into the mine with all his might and blow both of you sky high, causing you to wait 15 seconds to spawn before, on the last second, the enemy takes the last base and the game ends.
I say we turn on team damage only for bots >:(
