I found the problem to be AA was not being counted for DE.
Going to run it around again at some point.
Here's some interesting info:
Damage breakdown by percent (DRG Hard Rotation)
Code:
Autoattack : 24.80994403804434
Full Thrust : 13.427450699667673
Vorpal Thrust : 8.74680073415357
Heavy Thrust : 5.461454471204516
Phlebotomize : 5.696775002473597
True Thrust : 6.627933455030803
Chaos Thrust : 3.6600681026464557
Leg Sweep : 4.641830295724796
Phlebotomize (DoT) : 3.5361663693006506
Impulse Drive : 3.961845609934256
Chaos Thrust (DoT) : 3.8505354205518953
Disembowel : 4.714614754248133
Jump : 4.443250545214875
Fracture : 1.437419857378893
Dragonfire Dive : 1.30678245663098
Fracture (DoT) : 1.5256598485918367
Spineshatter Dive : 1.952095825620424
As for why the DoTs do less damage than their physical attacks, seems like something's up with my sorting algorithm.
