I would love an MMO like SWG again, especially one where there are classes that not only focuses on combat, this game is all about combat, which is what most MMOs are about. In SWG you could just be a crafter or even an entertainer. I really miss those type of classes, it made the game have more variety.
I think Smed and SOE can make a hit out of the ballpark with a game just like SWG but without having to be constricted to the lore of the IP or having to worry about Nancy McEntire -level morons deciding "We've decided everyone wants to be Luke or Han, noone wants to play Uncle Owen." thus bringing in the NGE.
