You didn't slot Convalescence? Are you crazy? Conva is very powerful. Those mega heals healers like to dump on you, those 15k Cure IIs/Tetras/etc end up being 20k instead, which is nearly half your health. Even more if it crits. I've seen Conva+Crit Cure II bring me from 10% up to 90.

And Largesse... dude. Again, that just.... wut? I couldn't imagine not having Largesse. Largesse+2 Medicas is a watered down healer LB lol.
