Eh watching the live letter I didn't get the vibe "Go play ultimate if you want anything engaging at all." it came off much more "If you really need to be challenged, well we have a certain challenging content you could try" those might sound interchangable but I dont think it was meant in a bad way.

I DO heavily agree though that the 'rotation' being so simple is super dumb. I think there are ways they can greatly add to it without massive button bloat or without lowering the skill floor and making it harder to heal. At the VERY least give us an AoE dot like Aero III.
