I played GW 1 but was never into organized PvP - more random arena and the Factions battles where you just hit play and never organized teams beforehand. I'll admit I sucked at it because I never had the patience to figure out any tactics besides going after soft targets
I like some of the movement mechanics they added into the game - jogging around and never being able to get over that 1-foot high barrier (unless you necro traversal or shadow stepped it that is) was a little dry.
