How about as a balance compromise tank healing was nerfed but we bring back active mitigation and channeled mitigation?
I think everyone agrees that
1) the tank being a proverbial ping pong ball between the healer and the boss isn’t fun for the tank
2) the healer being deleted by the tanks gross level of incidental healing isn’t fun for the healer
So what if we made the way tanks respond to mistakes more like the way healers respond to mistakes.
Healers arguably have the most “agency” of any role in the game as they are free at any time to drop damage to correct mistakes and they can use a lot of their heals in an attempt to protect themselves against the something that would have killed them. Tanks meanwhile have near zero agency but they have “corrected” this by buffing them so far they don’t need any agency because they are immortal. What if instead of just a ridiculous amount of passive healing the tanks could use mitigation that’s on the GCD or powerful channeled mitigation like say chelnion gate they can use to correct mistakes or protect themselves even if the healer is incompetent.
So rather than bloodwhetting just healing autos passively if your healer is asleep and you are getting chunked by autos you can drop a GCD to use a GCD mitigation to better protect yourself. If you fatfingered holy Shelton and now you need to soak a tower rather than desperately hoping the healer will recognise your dilemma and shield you you can instead drop 2-3 GCD’s to chelonian gate to survive the mechanic
