The removal of the original pvp flagging system was good, it was a terrible system. De-god modeing Jedi was a necessary change, they made pvp pointless. Questing and rep grinding were atrociously boring. Nothing really had a point to it other than just the sake of doing it.
SWG was good for its time but I don't ever really want to go back. I miss stuff like real player housing and real space battles but there's a hell of a lot I don't miss either.
