I've only read a bit of this thread, and I'm definitely not reading the whole thing, but I wanted to chime in regarding YoshiP's statement that healers should go play ultimates if they want engaging content.

I'm a sage main, I'm currently doing ultimates. Sure, the fights are "engaging", but it has almost nothing to do with being a healer. Some of the mechanics are fun, but that's more regarding actually dealing with fight mechanics and nothing to do with healing or dpsing. The comment he made is so disingenuous it's unreal.
