Think some players also got too comfy with Echo when running older extremes. The amount of times I got Shiva Ex in Mentor Roulette and the group struggled the first couple of runs, but once that Echo starts to build up suddenly your skipping mechs and half the party dying isn't that big of a deal. Unreal doesn't have Echo (yet) so you really do need to treat it like actual difficult content that isn't going to give you a handicap if you keep failing at it, and on top of that everything is pretty straight forward once you learn it anyway. No issues here, except with the rewards which several people have also mentioned.
