So, been working this floor for a bit and I feel it can be done (especially since it has been done). Let me start with my comp.

DRK & WAR
MNK & DRG (Driving)
MCH & BLM
AST & WHM

I'm curious. ASTs who've cleared A2S, what job was your healing partner? What did you spend your time doing on certain waves? What parts required a specific cooldown and why?
