Fine, Bloodwhetting is too OP

Personally, I'd say the only change needed is to make Nascent Flash only heal the target and not yourself. You're still able to make good use as OT, but doing so as MT would have real consequences. Saying this as the WAR from those ever-vexing WAR no healer dungeon runs.
Tanks being able to self sustain is fine, even if it's highly potent. If anything, DRK / GNB should be uplifted rather than PLD / WAR brought down.
However, spreading that healing to allies *at no compromise to their own* is what encroaches on the healer role.
