DRK's Sustainability and suggestions

[ADVSS]

. . .
How much did you play DRK then? DA+AD healing in trash pulls was one of the best things about taking DRK into a dungeon, because of how the two skills synergized with TBN and BP/BW, effectively allowed your healer to not have to worry as much about your HP because you were stealing from so many enemies.
Sole Survivor was used more for the MP on a dying enemy in my opinion, and relying on the heal it proffered is so far from what you should have done with the skill. At max level, with the ability just simply expiring, you only regained 20% of your HP/MP, and 30% if they died.

That DA - AD with BP in 3.0 was sick for mass pulls, when it was valid to them. But in a single target scenario, DRK has always been the lowest tier. It simply shouldnt be their identity at all, or ever, in any FF considering besides SoulEater. that is their only other trait. In FFXIV? Apparently DRK has to be the most dependant tank on healers, for virtually anything, even their ultimate. For reasons. Now maybe in the past our word "sustainablity" got mixed up with "MP sustain", but thats never what I meant when using the term. Dunno about everybody else. Pretty sure we were all on the same page though.
