How to Dragoon per Second: A DPS Paradigm

[JackFross]

I'm still struggling really hard to figure out how it's possible to squeeze out 100 more dps in Phases 1 and 2 combined to hit 1450 going into adds. Unless using a potion and NOT holding b4b for EC are all that's needed to do that? Would that be an extra 100 dps? These were the parses from my group going into add phase from last night.

My rotation for each of these was (more or less):
HT>[BL+B4B]>ID>[IR]>[BotD]>CT>[Leg+PS]>4th>[Jump]>Ph>[DfD]>TT>[SSD]>VT>[LS+gsk]>FT>4th>HT>ID>Dis>[Leg]>CT>4th>[gsk]>Ph>TT>VT>[Jump]>FT>4th>[gsk]>HT>[Leg]>ID>ID>{ID}>Phase (was always around 1500 here)

>Dis>CT>[IR]>HT>TT>[Leg+PS]>VT>[LS+BotD]>FT>[Jump]>[SSD]>4th>Ph>ID>Dis>[gsk]>CT>4th>HT>TT>VT>FT>4th>Ph>[Jump cancel]
[Living Liquid]>ID>Dis>CT>4th>[gsk]>[IR]>HT>ID>
[Liquid Limb]>Dis>CT>4th>HT>[B4B]>ID>
[EC target]>Dis>[gsk+BotD]>CT>[Leg+PS]>4th>[Jump]>TT>[SSD]>VT>[LS+gsk]>FT>[DfD]>4th>TT>ID>Dis>CT>4th>[gsk]>
[Other target]>ID>Dis>[Jump]>CT>4th>[gsk]

I might have missed 1-2 Leg Sweeps in there.

Last gsk didn't always go off, sometimes I forgot gsk 2 in phase 1. I end up getting 2-3 gsk on double hand, depending how quickly they pull them apart for Fist. Some of the runs also had it go Fist>Fist instead of Hand>Fist, but that just made me not double-dot; I'd use FT (with Life Surge) on the main hand, follow back to mid and drop CT on the opposite hand during Digititis, continuing from EC after that. Didn't really seem to impact much at all. (Those runs were the ones where the SMN is sub-1200)

Is there something there I'm doing markedly wrong/can improve upon to get up higher, or am I just "low" due to lack of Potion and holding B4B?

PS: Current gear that I was using for that fight.
