I agree with Connor that adding damage rotations to healers are a bad idea. Let tanks and damage dealers keep them because that's part of what keeps them interesting to play.

With healers, I think the additions of abilities like Glare IV are a better path. Make our abilities unlock other abilities which would give us a choice to use instead. That way it's not a true rotation.

In addition, I think the reintroduction of DoTs for healers only would be interesting because then we wouldn't be tied to the two minute meta. Instead, we would be dealing constant steady damage to contribute to the success of the party.
