By those links, all I see is that Guild Wars and Nightfall have the same You Say grade as WoW. Wich is a defeat, actually.
So please, back up your point. What exactly has GW taken directly from WoW, and what new thing did WoW introduce?
P.S.
You haven't played enough of GW if you think that PvP is all based on whether or not you can remove conditions or not. To explain it I'd have to explain the whole PvP system. Suffice to say, skill wins versus skill, because there's next to no gear grind.
