How is new AST feeling?

[MintnHoney]

Can someone help me understand something about macrocosmos.

So does using it after a raid wide still register it as well?

Using Macrocosmos after an attack does not record that attack's damage for Microcosmos. The issue you're likely coming across is that they want to use Macrocosmos as a oGCD, but it's actually a GCD, so it gets delayed instead of coming out when intended.
It's the consequence of it being the only spell in ASTs kit on a long cooldown, I think.
