Why have the level cap at 100? I'm having mine at 999 or so... I mean, when you think about it, if it takes months to level, it would be illogical that you'd ever reach level 100 in the first place.
You won't have "SSJ" players running around, because nobody will dedicate 10 years of their life in order to achieve that title. If they did, then that is really, really, really sad.
