I also really dislike that the dev team's idea of "more to heal" is adding mitigation checks to literally everything, being hit from 100 to 0 when the melee forgets to feint isn't exactly a great idea of more engaging healing.

Bring back stuff like the prey from A12S (heal target at least once or they die) or the autos that can crit from older content, or better yet, bring back tankbuster cleaves that have no castbar and can crit like in A9S. Just bring back more random damage and better designed fights. Take Neo Exdeath for example, he doesn't autoattack, he doesn't even move, but he was so much fun to heal.

Bring back all the random damage and expand our downtime kit and the healer role gets to have fun again.
