The Monk Temple

[NoctisUmbra]

My guild has several raid groups on turn 5 and their MNK use Fracture and ID in conjunction with BRD on every turn?

You'd need the Paeon, yea. I suppose it depends on the party make-up, since there can also be a demand for MP. It's not necessary is the point. The slight increase in DPS is not worth the increased dependency on BRD songs imo, especially when your healers or tanks may need MP.

They're just very inefficient skills. Especially in fights where there is no real DPS race.
