P1, and I played DotA heavily for years until the LoL beta. I still play a game now and then, but if I'm feeling nostalgic I usually jump on HoN :P.
EDIT: I won't be on HoN much until it releases and ranking matters as I'm focused on breaking into top 500 ELO in LoL, but I'm Da_Killah (BlackMage in LoL).
