I just want all tank jobs to have a comparable level of self sustain and DPS. I like diversity, but most important is for all tank role jobs to feel the same level of control over encounters.

Right now the gap isn't even close. WAR completely blows everything else out of the water in terms of self sustain, encounter control, and efficiency. It can fill its own health bar multiple times over WHILE doing good AOE damage. Nothing else even comes remotely close and has to struggle with more buttons and resource management just to do a fraction as well. These roles are tanks FIRST not "DPS that can take some damage" which seems what too many are content to think of them as. We have enough DPS jobs already. How about the few actual tank jobs are balanced to be actual TANKS?

The suggestions for TBN posted above are HORRIBLE, no offense. There is hardly any magic damage in this game as it is, and this actively makes the worst thing about tank balance even worse.

TBN is supposed to be the DRK equivalent of WAR Blood Whetting and it is an absolute joke. 25% health shield once every 30sec and it competes with your damage resource? Meanwhile WAR gets Blood Whetting on that same cooldown, it costs NO resources, and heals their entire health bar maybe 10x times or more WHILE they do damage? This is OK to people? Really?!?

TBN should lower its cooldown and refund MP if it breaks, and Abyssal Drain should be on a 30sec CD. Beyond that the devs need to seriously rethink their commitment to this role.
