Ok here is what I have for AoE:
The maths:
Each rotation is treated as one and done basically. The first HT is not buffed. Only CT/4th have Disembowel bonus. CT dot damage up to 3 enemies. TP Drain converted to GCDs instead of seconds (60 tp/3 sec = 48 tp/gcd @ 2.4 gcd). Different GK potencies based on 3 or 4 per min.
Potency/GCD:
Self-explanatory
Potency/Rotation:
The total potency of 1 rotation
Total Potency of rotations:
Total potency of both the rounded and full "# of rotations" (total pot & extended pot in spreadsheet). The IDC combos sort of skew this since you can repeat 10 times instead of only a couple
Conclusions:
Unless the pack is going to die in less than 30 sec, the best AoE rotation for longevity and damage seems to be HT/RoT combo.
