Morde
I am one of the fans of the shift that Riot is trying to make with a switch up to the traditional bot lane. The main problem I see with it is that if they want more champs to be used bot lane they need to remove the exp gain from Morde. It just sets the precedent that any non-traditional bot laner would need this buff to be comparable to Morde. I'm just imagining somebody like Riven/Darius with no shared exp and that is scary. No, this isn't the main problem with Morde (I believe it is his tank/damage combination) but it really just doesn't make sense to me that he can get his ability ranks up faster just by standing there.
