So returning player might be a little harsh, I never actually stopped playing, I just haven't had much time to play as of late, but I will in the near future, and I really want to hammer out NIN as a dps class.

I know the rotation, the openers, and what is expected of a NIN in a party. I've played this game plenty. But I want to know what other NIN's do to push their ability to the next level.

Disclaimer: I am an all content save for the latest savage player, so I have not yet played the newest savage Midas.

Specifically: 1- How do you treat AOE situations? Keep going single target? Drop dots on multiple targets? Anything fancier than Katon - Kassastu - Doton?

2- Is it really bad in using Duality on Armor Crush rather than Aeolian Edge if your Huton is low when Duality comes off cooldown?

3- What can a NIN do specifically to speed up dungeon runs in terms of killing speed with adds?

4- What other masteries of the job have you come across you'd like to share?
