I would throw in my two cents and tell you ho I do it like most Scholars I would believe. Prebuff the tank with Adlo and stone skin. Drop your dots on a mob and if there are others around use Bane to spread them. Your fairy and your prebuffs should keep the tank at an adequate level until you are done with this rotation. It isn't hard at all to do a bit of multitasking this way and you are not worrying about optimal dps just adding a bit to make things smoother. I can notice the difference between when I do and do not dps so I prefer to dps. As the true dps target mobs one by one I slowly drain the others of health and make the run faster. If the tank starts to drop below about 70% I stop dpsing and heal.

My main goal is to keep everyone alive so I always prioritize healing first. Dps comes second. Honestly I think if you do it a bit you will enjoy it.
