I could try again with Paeon to see how long I last. But, yeah, you probably won't have the luxury to go full-force for 2 straight minutes in endgame. w

I don't know the precise cutoff for a 6-fold rotation. With 2.05 GCD, the GL icon was vanishing during Snap Punch's animation every time only to refresh GL3 after. If you were 2.1GCD or higher I imagine you wouldn't have that grace period anymore.

To be clear: 2.05GCD is full DL (accessories included) and NQ Sphairai plus GL3. With food, HQ Sphairai, and Allagan/AF2 a MNK could reach 1.7 GCD. And if not, then certainly with SCH haste.
