I'm definitely feeling it with the O12S first phase fight. The DPS check is rather tight, and not running AST is pretty much taking away DPS from your party which at this point (which can be applied to both targets in the encounter), is essential to even be able to see phase 2 of the encounter.

I got the flask and the tomestone to upgrade my weapon after the reset, and I'm wondering whether I should upgrade my WHM weapon or just upgrade my AST weapon.
