I mean, you know how the role plays. You either go into it knowing that you might be a little bored during the healing downtime, or you play something else. You're not a dps, you don't need an overly complex damage rotation that'll punish you for stopping to heal.

It's bad enough that healers are expected to heal as little as possible in order to pump out as much damage as possible.

It's the "go go go, rush rush rush" problem that WoWs M+ has that keeps a lot of tanks and healers away.

If you want to have a full interesting dps rotation, then maybe you should play a dps job.
