I wud say Blitz U was but I can't really back that up because I know many people have been in a clan with him and he hasn't led anything close to be the best clan of all time. But I can say during my 3 years of clanning with him he did Gfx,Forums,getting (Minis,Preps,Inners,Organize Events),Call etc. He was a 1 man army but LOKI was a GOD P2P leader and I'm good friends with him.
