DRK feels super squish in comparison to the other tanks

I'm pretty sure Abyssal Drain don't heal that much on single target nor raid boss in high end content

The biggest change for lower levels in Dawntrail for ST heal was carve and spit heal gaining abyssal drain which was also not reflected in the video.
500 potency is still not nothing and it is enough combined with DrK's other mitigations given 60s isn't a whole lot of time as long as your cycling your mitigations. Prior to DT, in the video, AD was at 100 potency and C&S did not have the effect added, yet I was still able to self sustain even without.

For higher levels obvious the 40% mitigation free heal made tanking a breeze.

I do believe they need to rethink all mitigations because they put healers out of a job, and that includes outside of the tank role, so instead of increasing the floor I think we need to lower the ceiling.
