i find the gameplay of wow more entertaining but yes pvp of L2 is much better some how. but wow's one is much complexe.
i played L2 much more then wow for a simple reason, wen im not in my mod, and i want to kick somebody ass i should be able to doit. not search for the other "ally" if is right said.
and there are lot of kids too that swear you, and in wow you will not be able to hit him , bcuz is from same ally ( i mean Horde / Alliance )
wow is a legend too.
both are MMORPG so both will have similar actions. like friends in game , meet in real life and after marry together. i know some ppl from L2 and some in WoW that did this. and i know them in real life too.
