Dragoons: A Rotation Reborn

[FantasyForever]

I'm going to assume this is place to ask a question, cause I'm literally frustrated. I'm i94 (i110 neck, i100 bracelets/earrings/ring and levi weapon) and I'm only doing 300-310 dps in turn 8. I've sat on a dummy and used the rotations/ogcd abilities outlined on the first page and can pull 360+ w/o mercy stroke. Am I just bad? is there something I'm missing about this fight? I'm hit capped and just downright sad.

Are you using pots?

I'm sure you're not bad. Are you on Homing Missile/brainjack duty and nothing else?
In my group that's all I handle and I pull 389 at i105 using one pot.
