It's only T5 though. The rest of the turns are so trivialized that it's probably not much harder than the current ex dungeons. T5 is also trivialized by the fact that people are helping people get past t5. Regardless of the role of these helpers take on in t5, they're still adding into difficulty decrease on top of echo and item over level. Then they're free to go into the currently relevant second coil that are supposed to be harder than the previous one without echo. The expectations of the people you just helped and the people already in the PF for 2nd coil will be widely different. That's just fostering a PF board where the recruit rules are harsher and harsher.
