Yesterday I had a Prae run where I ended up dying to Ultima Weapon's first phase because one healer (WHM) was AFK washing dishes and the other (SCH) was only spamming Ruin 2. The SCH had forgotten to summon Eos and wasn't paying attention to my health so I spent the entirety of the phase transition cutscene dead. The SCH was also using JP for the cutscenes and was pulling the boss before everyone else could act.
