I've noticed that you don't get the extra xp when playing arcade, you should get that bonus imo.

And as i only play PVAI (i like having total control) I'd like it if the AI would pick bots at random. As it is now the bots on your team choose a character of the opposite gender. Like if i pick the shaman all the bots on my team are males and vice versa. Maybe it's only me that cares but what the hell might as well try.
