True but even on normal this wasn't an issue. And while I agree SD is better on normal, I'd still claim that it doesn't really matter - if the fight is done correct. During the tornado phase, I am actually the first one to get there but I guess the dmg from the tornadoes ain't that high on normal. Anyways, I don't see the big issue choosing one over another, both when it comes to SD/FR and elixirs/flask tbh.
Seems more like the OP did it wrong or the healers weren't fast enough topping people off.
