Funny thing is, I know hundreds of players that are playing GW2 only for the WvW. They prefer TOR combat but play GW2 because TOR has nothing to offer when it comes to Open World PVP.
This. People are even playing LOTRO for the Open World PvP over TOR. There are guilds with hundreds of players that left because of the Open World fail, but I know many would love to come back if there was some kind of Open World game.
