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

[fulminating]

Fundamentally it's all the same principle: tune encounter damage, player healing output, and mitigation tools such that more healing is required. The only difference between different tiers of content would be what percentage of cast time is mandatory healing/Esuna/etc and what percentage of cast time is wiggle room for player mistakes (fewer mistakes = more potential for DPS); as content increases in difficulty, there should be less of that wiggle room.

So what happens if a bad healer queues for something - is the party just stuck in the instance until they git gud or are kicked? We already know that abyssos managed to cause issues for pf healers between damage and body checks to the point that yoshi p asked people to try healer in a live letter. If normal content also gets tuned more aggressively then the impact must be more severe simply by the fact that there's more casual than high end content.

I'm also entirely certain that replacing 4 broils with 4 esunas is not really addressing the problem. It could well be that the hyper scripted combat encounters do not lend themselves to engaging healer gameplay, but they seem to have not intention on changing that.
