How to Dragoon per Second: A DPS Paradigm

[Leonus]

Would you guys dot 2 mobs with phlebotomize during the core of the rotation?

HT > Phleb (on an add) > CT combo ( on main boss) > 4th > Phleb ( on main boss) > FT combo (on add) > 4th etc, like in a1s?

I know HT wears off before FT combo is completely finished (on full thrust), but I was curious if this was a gain or loss overall.

Or should u just stick to the rotation, even with adds, and only move Phleb once or so, like dervy did in the vid that Thendiel posted.
