Fine, Bloodwhetting is too OP

Isn’t this only considered the downside for tanks though?

If you nerf tank sustain then there are downsides, for the tank.

That already seems true basically only at min ilvl. By max, our sustain frequently renders parts of itself redundant unless purposely avoiding whatever AoE healing is required. When not tanking Expert Roulettes myself, I've often asked the DRKs who had the other tanks leveled why they run on DRK. The most typical answers: "Because it looks coolest," and "Because a larger part of my defensives actually matter."

Asking for encounters to be even remotely proportionate to the strength of tank/healer abilities is ‘closing the door to jobs stepping out their line’? Or maybe it would actually give a modicum of justification for the many, many healing support abilities dps have.

Food for thought:
Tbf, this is complicated by the fact that even though healers have very similar free sustain outputs, that still leaves distinct tuning targets for using the full amount of jobs' free sustain even when fully geared across Healers/Warriors/Paladins/TheOtherTanks, and healers themselves vary in maximum available output if not limiting oneself to free sustain alone.

Tune a dungeon for Warrior and maximum AST ST sustain and you actually will have closed off the ability for anyone else to clear, for instance. That's the literal most extreme tuning possible that a tank-healer pair could theoretically pass without dps support, but it'd also be quite a step until the next tank's available output in dungeons.

It'd be kind of like if there were only one DPS in dungeons, as per tank and healer, and you had to simultaneously balance damage requirements for Bard and Samurai. But with a yet larger gap, and with only two real contributors (to sustain) instead of 3 (as to damage).
