Warrior is amazing at level 60. I'm a former paladin (MT'd all the Coil trilogy as PLD), then switched to WAR for the 3.0. Best.decision.ever! DRK is actually fun to play too. I've been tanking in a lot of MMOs and I like the way tanks here can do more stuff than just tank. I love the idea how they can try to maximize their DPS as they balance it with their mitigation skills. You feel truly useful for your group, no matter which job you play, either if you're maintanking or offtanking.
