I get that I am the "healer" but see comments and suggestions for everybody to have potions or antidotes when a situation calls for it. I do try to stay on top of it but Esuna is not instant and regen is slower healing so losing 1000hp in one sec is not something it can keep up with. Even with presence of mind cure spells take 2 seconds. I was apologizing profusely with the first boss but I was questioning the strategy of laying everything on the healer, especially since I was still getting familiar with this dungeon and even told them I was a first timer.
