So I hear Monks have a fairly strong AOE rotation, so i'm asking the community for some advice.

Specifically in A2(S), there are a lot of mobs to deal with, and some strong AOE damage can burn them down pretty quick. Right now my AOE opener consists as such:
:

form shift to Coeurl, Rock Breaker > Perfect Balance > RB > B4B > RB spam.
Then I continue to use FoD > Twin/True > RB.

I think this works, but in A2 I run out of TP extremely fast. By the 3rd wave I'm already drained and Purification and Invigorate are gone.

Does anyone have any tips on a more efficient way of doing AOE damage as a Monk?
