A summary of healer issues

[Kabooa]

That's literally why Raise and Cure are Variant actions: So that you're not required to take a healer in with you. That is by design; no news there.

Here's my question, though: I went in as a two-person party, me on tank (PLD), a friend on healer (SGE). Funny thing: We had almost the exact same max HP. Mine was what I expected, which means my friend's/the SGE's HP was scaled up by quite a bit. Does that mean their damage was also scaled up, meaning they wouldn't be as useless as you might otherwise think?

The HP of the boss scales depending on how many players enter. It's possible that the HP might scale up depending on number and job, where tanks and healers increase the HP by less than a DPS would.

Criterion absolutely requires healers though.

I highly recommend doing Criterion completely blind. It is some of the most fun I've personally had in this game.
