I do agree that we are not putting enough emphasis on our experiences with DRK being dependant on the healer.

You can have great runs in dungeons as a DRK with a switched on healer, I do it often..now, anyways, after addressing my own issues in using DRK, much more stringent use of tool kit required in EW compared to Shb I find, probably due to iLvl more than anything. I have no shame in admitting I was the issue for a time xD

But likewise you can have terrible runs with a green dps/inexperienced healer...and this is where tanks are truly made and where DRK, imo, falls short, because none of the tanks struggle when backed by a solid party.

I just feel like it has no way to deal with less than perfect healers if it needs to unlike other tanks, who can be just that bit more independent (or a lot more independent in WAR's case). Maybe that is by design, a trade off for solid performance in trials/boss fights. I don't know.

But I would love a little extra something in the form of HP recovery added to the toolkit. As suggested, shorter cooldown AD would actually help a lot. Or maybe a regen added to Oblation?

I don't think you can do much to TBN without pushing it over the edge in end game content, it's already very solid there and DRK could FAST become the 'must have' with its already good dps if TBN was to get buffed.

Just my opinions.
