How to Dragoon per Second: A DPS Paradigm

[Baa]

What kind of rotation are you doing? Mind to elaborate it a little bit more?

The same one detailed on the first page.
The reasoning for 2.40s GCD is to make sure HT doesn't drop, letting it buff the next HT:
HT(2.4s used up here) --> 9 other GCDs using up remaining 21.6s of buff --> HT again on the dot

But HT applies ~1s into its own GCD:
HT(~1.4s used up here) --> 9 other GCDs using up 21.6s of buff --> ~1s leeway to HT again
