It really isn't that much harder than Amaraut was when it was released. That and most of the mechanics that do happen in that dungeon are survivable if the healer remembers to actually use esuna instead of just running around and healing all day. The only mechanic that can be a bit of a problem is the double aoe on the final boss, since everyones gear is level synced and the dps have low defense, so if the healer doesn't get them nearly topped off and/or the tank and maybe a caster uses their mitigations, it can result in the dps just outright dying.

However, I've not really seen the double aoe deaths for months and mostly see people dying to the second boss due to misjudging the missile fire. The first boss is kind of rough if people haven't seen the mechanics yet and the healer doesn't normally esuna.
