Impressive mind reading. And completely wrong. I do engage in hard mode and watch Incarnate trivialize them.
Example, I was on a PUG 4 star Aeon. The only organization was a request for a debuff, tank, and dps. Not specific power sets just a general type of build. And T4 Barrier.
The leader was very experienced, they cycled Ageless and the rest of us cycled Barrier. Cycling Barrier solved most of the durability issues. DPS is almost never an issue with all the Judgements, Nukes, and procs, topped off with a layer of debuff.
Completed in 1.5 hours, had two party wipes during "special fight", that the worst of it. For a PUG.
I have harder 801 runs than this 4 star hard mode.
