I find the fact so many people have commented poorly about this champ being an AD carry sort of funny.
Personally, I've always liked the idea of actual teams. Noxians vs Demacians, for example. This just means that there is more opportunity for this to happen. Until Draven, Noxus didn't really have a ranged AD carry. There were mercenary champions they could use, but no actual Noxians that could fill the ranged carry role. Draven will be the first.
It's rather like how Noxus really didn't have many standard "fighter" choices. Sion and Mundo, that's about it. While Demacia had Jarvan, Garen, Xin and Poppy that could all fill the role. I'm glad to see a Noxian AD carry. Now if only Demacia could get a real burst assassin.
