Well, right now, in the beta the Arms Warrior still have a bleed DoT but it no longer requires an activation. I prefer it.
As you might have guessed, I'm going to focus my Beta time primarily on the Warrior.
Also, I personally believe that if you spec your class for DPS, whether Rogue, Warrior, Mage, Warlock, Paladin, Priest, whatever, you should have a chance to be top DPS. It's not the class that makes you a badass. It's how you use it.

I have issue with the talent system. The level 70(?) choices are all defensive stance based, but there's also a severe lack of defense based talents for the other levels. They need to spread them out.
