League of Legends (LoL) Question: Karthus jungle?
In the most recent Pro Player Pick, Archie mentioned that one of his favorite junglers to play with is Karthus. I've heard of jungle Karthus before, and that it has been used by some pro team in the past (just can't think of the team), but I really didn't understand why he said jungle Karthus like its an ordinary pick. Is jungle Karthus popular in Asian solo q? If it is, why haven't I seen it in NA?
