In endwalker, tanks are currently very strong in sustain and mitigation. In dawntrail they will receive yet more mitigation and healing on their “30%” mitigation as well as a buff to the role action reprisal and a healing received bonus from on the role action rampart.

I have some concerns about this; how hard are you going to have to hit the tanks for this to not be enormous overkill, due to this necessary higher damage in the event of a tank death healers will struggle more to keep the dps up and recover- an attack that would do 100 damage to a dps has gone from doing about 60 (after tank mastery and vengeance) to about 50, and finally if the incoming isn’t increased to take advantage of the mitigation and healing buffs then healers will become more vestigial. 1/0/3 runs of dungeons are already easy and more efficient than the recommended composition.

I would have thought that reducing tank sustain, incoming damage and free healing should reduce the difference between the truly awful tanks/healers and necessity of having at least one semicompetent support role to carry the party?
