This is called primitiveness. For those who've been played various MMORPG for a time and isn't Star Wars fans it's boring. Need something to make fresh feeling. And class quests is the good example here. Technically all quests are the same but character storylines are interesting and comparable to the standalone literary works. It's what makes fresh feel and keeps hooked. Deeply worked dialogs with some effect on the game depending on reply variant (at least the most minor effect but something) could to make fresh regular quests. Now, speaking for myself, have been playing various MMORPG for about 6 years and not Star Wars fan, i'm not going to continue subscription after a month which comes with the game.

I don't share a such experience with SW: TOR but i share a lot of such experiences in general as not in every country you may expect nice and polite service. So here's 2 ways to deal with it: to move alone and leave everything as is or to contact management and let them to know how "nice and polite" was their employee. Commonly, managers are more interested to hear about your problems (and to solve them) than support guys as for them you'r a client who brings money and for support you'r just more work for the same money.
