Dear Dragoons. Your AoE is actually good.

I might be missing it, but it seems you've forgotten Ring of Thorns. I'm also definitely against AoE spams because they reduce DoT's and piercing debuffs, but position bonus for RoT is 150. Assuming I score that bonus, I at least try to work it in whenever I re-apply HT. So, I guess my mob rotation would look something like this:

Heavy thrust > BFB > Ring of Thorns > Internal Release > Impulse Drive > Leg Sweep > Disembowel > BotD > Chaos Thrust > Lifesurge > 4th Tier Combo > Geirskogul > Doom Spike > Phlebotomize (in the unlikely event that the primary targets is still alive) > Power Surge > Impulse Drive > Jump > Disembowel > Chaos Thrust > 4th Tier > Doom Spike > Heavy Thrust > Ring of Thorns > etc,

I treat Ring of Thorns and Doom Spike the same way I treat Heavy Thrust and Phlebotomize in my boss rotation. The work in opposite positions. 1st combo = HT+RoT. Second combo (which would normally be the phlebotomize one) = Doom Spike. I typically stagger my oGCD's between GCD's to maximize speed and use Spine Shatter Dive or Dragon Fire Dive to quickly hop between targets. A second Geirskogul is used at 21 seconds of BotD buff, or if the mob is almost dead and I'm going to lose the buff anyway. I don't really know if this is the "right" way to do it, mind you. I don't main Dragoon. I only moonlight as one. It has been working for me so far, though.
