Last I checked the tank was part of the party. Why is the tank exempt from this. “The healers job is to heal the party not the tank” just reads as the tank wanting to be exempt from the party responsibility of relying on others but still having the rest of the party rely on them.
I don’t put all the blame on tank sustain, I put a hefty majority of the blame on tank sustain because it’s a hefty majority of the problem. You act like I’ve never viewed DPS sustain as a problem as well. I was the first one out there laughing at how overpowered SAM’s new defensive is or why the hell the DPS needed second wind upgrades or why SMN needed lux Solaris. I love how you go “the trinity isn’t broken see DPS can also replace the healer”. That isn’t an argument, that’s an admittance the trinity is beyond broken.
And again if all healing is random AOE healing the tank doesn’t care about then where is the single target healing being used.
Your entire point seems to boil down to “let ME do what I want while the DPS and healer rely on each other”. Tell me in this dynamic you are describing where are you relying on other party members, what are they doing that you can’t do because to me that reads far more as ego than healers not wanting the tanks to do their job for them
