[@Leolycan] We have like six mid laners and two supports... but Ekko is fine. XD
 I can just see Matt beating everyone over the head with a stick as he tries to get them to listen to him. XD

That's a way to think about it. Rood to top lane and ADC Thresh, Diana Jungle, Ekko Jungle + Support, Ahri Support, Assassin Kill Lane, Mid Lane + ADC Bard, etc. Not to say that things aren't seen more consistently than others, but the possibilities are there. It's people that don't use them.

It be more valid to say that we have four typically AP champions, two typically AD champions, and one typically tank champion. Although, this is my two cents on that. :p
