Two things what I hate about the the so-called 'best MMO' Guild Wars 2:
1. You don't walk. It feels like the world is being moved from under your feet instead of you actually walking and that your character is floating somewhat above it. In SWTOR, walking feels solid and footsteps sound different depending on what surface you're walking. It might be a minor thing to others, but it annoyed the heck out of me.
2. No interaction with other players. Sure, you do these random quests with sometimes dozens of other players, but in the week I've played it (intensively), I've never talked to any other player. Once the quest was done, everybody went on their own way. The so-called revolutionairy quest system fell hard on it face, at least for me it did. I'd prefer the old school way, like SWTOR does (and I'm an MMO noob, with SWTOR being my first MMO in december 2011).
