Simple question, simple answer.
Drk is one of the higher dps tanks next to war, they have good utility and defense. They will keep their Mt spot as long as pld dps stays low like it always has.
Drk is also getting a few strong hitter skills.
They also have the best animations out of all the tanks, best armor, best weapon etc.
The changes to pld are quality of life and not damage increases, drk is getting strong dmg skills and some utility, making them even better at dps.
Drk has on demand magical mitigation, a short cooldown gap closer (plunge) lots of Ogcds, better reprisal, reliable stuns, Int down, they have lots.
Drk is looking pretty great, hold onto your horses, the only tank that can come close to your dmg is warrior and they are adjusting the dmg of fel cleave anyways and they mentioned toning them down with removal of storms eye debuff etc.
Holding agro is easy on drk, they also have 2 resources mp and tp so they are rarely resource starved unless you spam something.
