One of the nice thing in later wow (havent tried pandaria) was the phased events. Could easily have been done in swtor too. after finishing planetary questline you would phase to "planet2" where bonus quests would be. It helped moving the story forward in the areas.
And yes. SWTOR miss some mmo features.. itīs small things that you might not notice at first, but when you log into GW2 ex. the world feels more alive. Itīs the tiny things like when you walk onto a farmground and the chickens go cluck cluck. Itīs too bad i like swtor better. Much of the fluff things is just done better in other mmoīs. And lets face it. mmoīs needs loads of fluff. Itīs not like a singleplayer game you play once, if itīs good you might replay a few times. People spend so much more time in a mmo that more fluff just pays off.
Yeah and SWTOR lacks that fluff. The single player feature dominates almost everything else in this game, which is REALLY BAD.
