NIN Rotation help ?

[Lyrinn]

NINs run on a priority system.

1. Huton (AC)
2. Dancing Edge
3. DoTs
4. 1-3 are already done and have nothing else to do? AE.
1-4a. Hit oGCDs whenever they're up. This includes ninjutsu (Suiton/TA > Fuma/Raiton spam until Suiton is back up).

The only "long rotation" you should be mindful of is the opener and that's because people have determined what the optimal sequence of oGCDs is when everything is up. Even then, you can just follow the priority system, botch the specific ordering and still do decent DPS.

The optimal opener also requires knowing when your tank is going to pull (as you want to have Huton up for ~20 seconds, allowing you to open with Suiton, so that you're not hitting a 3-step Mudra while BfB/IR are up), so it can be difficult to perfect outside of scripted situations (generally static/pre-form parties). Following the priority will keep your DPS solid even without the perfect opener (especially since the opener's effect on overal DPS tends to flatten out once a fight's gone on long enough).
