Aphrodite, SSR Nike... uh, Amaterasu...? Sol. All SSRs. Well, I guess we can count SR Nike and Brynhildr (200/t) as the latter has more healing output than Amaterasu (171/t).
With Andromeda, I auto-skill soloed Expert101 this morning and I don't even have any heal boost... then again, Fire is my secondary element at 88% weapon grid currently. Also 70 Brynhildr, Agni and Amon is fairly good for a non-SSR group, so maybe it's not fair to compare. And I have no idea how lucky I was with Sniper Shot and/or Overdrives, it's not like I followed the fight.
