I see what you mean. I didn't have the problems you mentioned because I really don't care about MMO side of the game (end game PVE, PVP, interaction with other players). All I care is the single-player content (i.e. class storylines) which is great and extremely extensive. In fact I tried hard not to interact with other players, because that kind of pulls you out of the story and Star Wars universe back into the real life. So basically when I finished one character's storyline I just moved to a new character.
So in this respect SWTOR great differs from WoW. I could never play WoW because it has little to no storyline content. I really don't see fun doing some PVE/PVP stuff with other players, which WoW is all about. I would say SWTOR is primary a single-player game with a some MMO aspects.
