Here's another one - Tol Dagor +8 in time with a mixed team:



As for the Shammy healer, I have gotten to the point where I think they are my favorite healer. The Spirit Link totem is a great, "Oh Crap!" button to stabilize a bad situation (that I should really use much more often than I do). I love having a healer with a low-cooldown interrupt, since they are so important in Mythic+ dungeons. Spamming chain heal is a nice way to get the whole party up fairly quickly. I also have them throw down a capacitor totem during my AOE rotations which helps on big trash pulls. They do pretty good DPS while healing as well (especially with a 1-2 Igneous Potential Azerite traits). However, they are NOT that mobile and have no battle rez, which I definitely miss sometimes.

It is fun to have all the max level and geared healers so I can just play around and see what works best.
