I've always enjoyed the spot healing aspect of our play with holy shock and EF instant heal as well as great tank healing which I feel has always been one of our main roles in raiding since way back. But the changes over the past few patches have really slowed down our healing style I feel. I would've been glad to see a nerf to the HoT which would mainly make us look worse on meters rather than a nerf to the instant heal which will be worse for us in terms of being useful healers.
Back in 5.1 when our class was not effed tho we complained about not having enough AOE heals and I think to an extent this was addressed but the changes are always kind of roundabout. I think we shouldn't be too down tho, if Microsoft can roll back their changes maybe Blizzard can realize the real problems make some useful changes
