GW 2 is pretty...uhm...average. Putting aside the bugs in beta, I still would rather play the certain shit panda game if I wanted to play a fantasy MMO atm.
SWTOR, on the other hand, is fucking awesome. I only PVP in it, cutting imps to shreds sure is fun.
I don't think selling credits is worth it tbh, I always have a few mil credits, and there's nothing to spend them on in the game atm. PVE players need repairs, that's about it. Once you augment all your gear, credits are useless, and you can easily maintain a high enough credit bank by sending your companions on crew missions while you play the game.
