This happened a while back but I remember when running through Ravana as a 53/54 AST and one of our healers falling off the edge halfway through.
I had to solo heal the rest of the fight and even though we likely had more deaths, everyone was patient and would often make sure they stayed close to me so it would be easier to heal (when they could. They obviously spread out during mechanics that required it).
I even had SMN helping me raise people. Although it was stressful and I was mashing buttons the entire time, it gave a boost of confidence knowing I could do that. The communication of the people in PT helped.
