Depends on how effective Stormcaller is battle but I really love my Sunsinger and not because of the revive aspect of it, I actually don't like having to use revive over Radiant Skin as I play aggressive build and I often use my super to clear out an opposing team rather than save it for a revive (although this changed depending on the skill of the team we're playing against). Still i'm really loving the look of the Stormcaller and I gotta try it out in ToO just to see how much damage it can do. I think a lot of people will be using the new subclasses and nothing else in the coming months as they seem to be more powerful but they have mentioned they might upgrade the older subclasses to match the new as they might be a little underpowered in comparison so personally i'm hoping this comes sooner rather than later.
