I played wow from release day until wrath was released. I was in the number 1 horde guild in the US, top DPS warlock back when the game was hard. I've beta tested at least 7 different MMOs and I have to tell you that this is the best one I've played so far. There's a lot of hate going around that it's just wow with star wars skins. That's not really the case. This game is very different. A lot of the features wow has were stolen from other MMOs. This one is by far the most fun I've played PVP wise. I'm not 50 yet so I can't truly comment on the end-game yet, but so far I'm having a blast.
Me and a couple of the GGA/chicago guys are playing on Nadd's Sarcophagus on the empire side.
