Completed it with a WAR/NIN/NIN/WHM party, didn't really need to coordinate pulls (anyone pulled) until around floor 43, a little on the easy side to be honest, easier than most dungeons. I feel like they should have a save point before each boss, but make the bosses quite a bit more challenging, on par with Alex normal maybe, at least for level 50 and onwards.

But otherwise, very enjoyable content, not sure if I'll do it again though.
