the normal content is too easy

Ifrit/Garuda and their love child boss (E6S) were harder than Chadarnook, but that’s a low bar to beat.

I'd also posit that an unfortunate amount of E6S' own difficulty may have come from the arena design; I know a lot of people who didn't know they had partial colorblindness until they discovered they literally could not see the wind nails against the arena floor.
