How is new AST feeling?

Can someone help me understand something about macrocosmos.

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

No. Using macrocosmos gives every party member you hit a buff. This buff stores 50% of the dmg taken (even dmg done too shields) and converts it at the end of the buff or when you recast the spell into a heal equal too the 50 % dmg you took.
