I dunno 'cause even pve pretty much sucked.
Pretty much the newer dungeons like geonosian cave and DWB etc.. (and newer stuff added since I left I suppose) were the only pve content that even had a purpose. Every other dungeon and quest that was created at the start was pretty much a buggy piece of shit with no purpose, no unique loots, and no benefit to playing them. 95% of the pve content in the game was bugged in some way. So you would get to the end of some dungeon and find absolutely nothing there. Or at the most there would be some big ornamental chest that I'm assuming was intended to have nice stuff inside, but instead it has the same crap the meatclump thugs outside the cities drop. There were tons of cool dungeons that could have been something if they would have bothered with it. Like for instance the volcano on Lok with the cool trade federation droids. Many people probably don't even know of it's existence because there's no point of even going there. Sure you can kill cool new droids that you can't find anywhere else, but why the hell do they still drop the same old crap cdef pistols as everything else!? Sheesh!
Then lets not forget that there are 2 types of missions: kill everything at some coordinates, or delivery; which every fracking npc mission falls under, none of which ever have a point. Not to mention all the dead-end uncompleteable missions. There were so many damn bugs in this game that are obvious to anyone who bothers playing it. It seems like a simple concept: after creating content, log onto a damn account and try playing it, and if it doesn't work then log back out and get to programming to make it work. But no, of course they never did this and hundreds of game-killing bugs just sat there forever, still there to this day even. It was rediculous how unpolished this stupid game was.
