That and the game just came out and no one really knows how to play the game. From my experience MMO players are some of the most anally retentive, perfection seeking, overly complaining bunch in all of gaming.
Another words, I care less what the group complaining now have to say, they're the impatient ones that get mad for dieing twice in a row in their first PvP encounter, and base all their judgement on that little bit of experience. =/
Give it a month or two, and once we see 5 page + analyses from players that know how to evaluate a game, and are capable of explaining thoroughly the pros and cons, that's when it's time to take heed.
