Patch 3.05 up... NO DRK rework!

[Krr]

Dark Knight is not meant to do as much damage as a Warrior or defend as well as a Paladin as it is a hybrid of Offensive tanking and Defensive tanking.

This is wrong - the the stated tanking styles of the three tanks in the Letter From The Producer is warriors as having more MT damage, Paladins as having superior physical defense, and Dark Knights as having superior magical defense. It's also implied that their OT DPS should be comparable to Warrior's if someone is providing a slash debuff. Of course, right now, that's all DRK does when offtanking, if a Monk is present.

The big takeaway here is that MTing has a decent, if deeply fragile and tenuous balance between all three tanks, and OTing is so hilariously dominated by Warrior (despite obvious attempts to diversify it with DRK joining the game and paladin's new toys that can be used while OTing) due to their irreplacable extra utility and ridiculously good DPS.
