I'm probably not the first to ask, but I'd like to hear thoughts on this. I'm trying to decide which one to get CoV for next. I feel like the clerics ability to insta rez the tank is pretty big and saving wipes in tough content is more useful than the shaman buffs. My groups tank doesn't seem any less likely to die with the shaman as healer in my experience. If it helps, I use CWTN plugins for basically everything.
