I was hoping it would be a different kind of challenge than the other high-end content in the game. It's basically pattern memorisation raid bosses again. I gave it a shot with random people on the first day but my party disbanded when they realized what kind of content it was. Now I see people's strats and diagrams on reddit and I know it's not for me.

It's hard but not impossible to come up with ideas that aren't just team jump rope bosses. The deepest floors of deep dungeon are about carefully navigating around traps and roaming enemies, and conserving limited use items/buffs. So it's possible to make content that is a bit challenging without it being basically another raid.
