You posted in the correct section so it's all good
Hmm... it sounds like you're using .dmbot files in the bot manager, am I right? I personally dislike them for the same reason that you're experiencing.
Try using some of the built-in bots in the dropdown box on the bottom of the screen. Start up Doomwood rep or another reputation bot, wait until you get rank 10 and then you'll get new classes
Doomwood rep is a good place to start.
