i wanna find a mmorpg that is very hard and requires skill to pvp and such

doesnt matter if its free or not

Very hard to what level in? I know for a fact that as far as P2P mmorpgs go I would say World of Warcrafts pvp system centers somewhat around reaction time and then equipment/tactics.

If your looking for a game based mostly on PvP I would say planetside but its an mmofps looks like tribes you might like it www.planetside.com
