Mike Zadorojny, Content Designer on Guild Wars 2 took some to chat with us at PAX Prime 2011 about the innovative MMO's crafting and combat systems. In Guild Wars 2 you won't need a dedicated healer, and you'll be able to discover new crafting recipes on the go. Also, according to Zadorojny there will be a GW2 closed beta by the end of the year. I hope I get in!
Guild Wars 2 is coming out exclusively for the PC when it's ready.
