That Instance has 2 healers per group, how is it the fault of 1 Healer? Anyways I do agree healers are very important roles and you have to bring your A game in all Raids you never know when the party will wipe. Sometimes even carrying other groups.

You cannot snooze yourself through a instance especially this high end like Ivalice. If aTank or DPS dies it’s a no big deal if a Healer dies your party loses its healing and they call can die. You weren’t in the wrong if the story told is 100% correct
