There will never be a mmo released that will satisfy everyone at launch. Look at TERA, that game was a breath of fresh air in the mmo world, but then it died after four months because the end game was... well, there was no endgame. Now, it's more popular than it was before. Just give ARR time, they are using a phoenix down on a failed game and trying to make it their own. Everything with games takes money and time. Even if we were given 20 classes from the start, people would still be complaining about imbalances, lack of skills, and whatever else they can think of after powering through the game.
