Nin rework suggestion

[IBLazORI]

There's so many mistakes in your suggestions that I don't know where to start, organize your thoughts before posting anything next time.

First or all, you say you want 1 button mudras but you talk about 2 and 3 mudra abilities right after, doesn't make sense. The only thing I'd change from mudras is simply remove the cooldown if you fail a combination and being able to weave signs while using other skills.

Second, if Shadow Fang was part of the main rotation you would be refreshing your DoT all the time, doesn't make sense either, take a look at DRG for example, it has 1-2-3 dmg combo and 1-4-5 buff/DoT combo. I would make Armor Crush being finisher for Shadow Fang though, that'd be nice.

Third, Dream with a dream should be used along Trick Attack and Assasinate and I personally love that 3 hit combo, they all share the same cooldown and are the biggest burst damage NIN has.

the 1 button mudras are for helping with rotations and clipping issues due to ping issues. right now you use either raiton (2 buttons) or Hyoshu Ranryu (2 buttons)and both are clipping which could lead to more dps if clipping was being avoided.

The 2 button combos:
Doton and Huton wont be used in a raid situation really, the only 2 button combo is Suiton for trick attack This helps with players with ping issues.
The 3 button combos won't be used during battles anyways(huton).

So i'm not sure what you were confused with?

Currently suiton is a 3 button mudra and clips. Reducing it to 2 button will reduce the amount of clipping.

You would not be refreshing your dot all the time. Shadow fang applies a 24 second dot and armor crush refreshes huton by 30 seconds.
I must be missing something where you state that it will be refreshing all the time. You would just be reapplying shadow fang like your normally do but with the added effect of extending huton. Seems like a win win to me, unless im missing something.
You would get an extra rotation of your main 1-2-3 combo in instead of doing the 1-4 then 1-2-5 combo
