I'll second that: Neverwinter's gameplay is one of the best I've seen in an MMO. The capitol city was terribly laggy, but the combat felt __very__ satisfying. Unfortunately, the few people I talked to indicated that there were some class balance issues -- I took that with some grain of salt -- , and my pocket healer expressed a lot of frustration that as a cleric he couldn't really healbot. Healing mechanics requiring you to face people to see their health didn't make it any nicer, he said.
We're hopeful that Elder Scrolls Online (beta soon!) will be nice.... but honestly I'm not eager to maintain two subscriptions, so the bar for awesomeness is that much higher.
Go where your friends go, though. If my guild rolled to a different game, I'd go with them.
