ID fits well if you're in burst mode knowing your grease is going to take a dive anyway. Internal release and bfb, howling, peak, etc for instance

Basically a finisher.

You are basically stacking as much potency as you can situations for ID. Or perhaps you're being screwed and the only saving grace you got left is bloodbathing it.

Theory crafting aside, battles don't start mattering till 80% in, and only need to get your mojo on at 50%. And that's when pretty much every classes' damage goes down and rotation goes to heck. There's no right answer to the best rotation because it shit happens and junk when you hit the last half of the battle.

I could care less if a mnk is bootshining auto bot or doing some crazy non repeating squence of combos at the start of the battle(that's when the boss rolls over for you), and it should really only matter towards the end when you probably have half the party dead, and the other half running around like headless chicken.
