It's hard to learn anything against a bot that uses an opener out of a list at random, and that's pretty much what "fight school" is. As ironic as it is I don't think the fight school is supposed to teach you how to be better at Toribash in general as much as it's there to put you in a situation that needs you to adapt at least a little bit so you have a platform to build up from as a player. There has to be some sort of transnational period between kicking the shit out of a lifeless Uke and getting destroyed in multiplayer.
