That's not what I meant, I know DRK will have a tank and dps stance. I was talking about party/raid buffs. WAR has the "enemy takes more slashing damage" debuff, which is functionally an offensive party/raid buff as it increases damage output of the raid. They stated that they will be doing something to PLD (maybe its Divine Veil?) so that they can buff the defense of the party/raid. That leads me to what I was wondering, what kind of party/raid buff type of stuff will DRK get? Will it be offensive focused like WAR or defensive like PLD or something else entirely and how will that effect the party dynamics of different tank combinations.
