The changes to Astrologian are upsetting

[Aravell]

I barely put thought into Abyssos beyond a handful of mechanics and... newsflash. If the only time you have to consider using single target abilities to be 'mandatory' is a few instances in an entire expansion's worth of fights... odds are they aren't that useful.

I remember that the only parts in Abyssos where single target focused healing matters were Natural Alignment and the Ifrit DoT during High Concept 2 (Because those were the only mechanics I remember using Fey Union on).

The DoT busters in P5S, P6S and P7S were an utter joke if the tanks cross-mitigated reliably. Like if a DRK and PLD crossed their mitigations, you don't even see them take damage.

That said, it's a different story in PF. I've seen some really bad tanks in P5S, like a WAR that died to 1 tick of Toxic Crunch, but that's not the norm, and I think a tank that barely mitigates isn't possible to save either way.
