How would you solve the boring "damage rotation" of the healers?

Again, remember that we've had prior history with this, and it got nerfed into the floor in a hurry. I'm not swinging my own opinion around, I'm gauging my thoughts based on SE's previous actions from back when we had a alliance boss that was a bonafide healer competency check.

Diabolos in Dun Scaith says hello, still putting tanks and healers in their place.

That kind of incoming damage everywhere else would absolutely alienate casuals.
