I'm a Paladin main, but I do play DRK in O6s right now because that second last kiss is rough on Paladin and DRK has mitigation options galore in the fight. In my opinion even before this update DRK was in a pretty good place especially on bosses that deal magic damage. The only thing it was lacking and sadly still lacks is raid wide mitigation options like a divine veil or shake it off. There is a lot of raid wide damage this tier so I would still have DRK 3rd for Kefka and God Kefka, but if we do have any raids with more single target things to mitigate and magic damage busters DRK will be the preferred tank.

Every time my sheltron gets taken off by an auto right before a tank buster I am so jealous that DRK's have Blackest Night.
