little NIN throw idea

Hey this is a copy from a post i did on reddit about a little idea i had for NIN.

After watching some of the older FFs recently, it kinda struck me that some of the more classical NIN/THF abilities could be better implented or synergized with a few little tweaks.
For example throwing. In older FFs you had the option of throwing shuriken or other weapons at the enemy for high dmg. Now in FFXIV this is kinda implemented via the shuriken ninjutsu but it gets little use for such an iconic ability since the mudra fix because raiton is stronger.
Another thing is the steal command, which is obviously difficult to implement in an MMO (because economy) and mug does a fairly poor job of representing it.
Now one way those two abilities synergized in older FFs was that you could steal stuff first from an enemy and then throw it at them and imo this could be implemented really well in FFXIV.

Here is my idea:

Mug would have a decent chance of proccing ("stealing") different stuff, which would then alter your next shuriken ninjutsu to throw something else rather than a shuriken, for more dmg.
Say you could for example mug ("steal") a sword, which would give you a stack of sword, turning your next shuriken into a throw sword ninjutsu for overall more dmg than raiton.
I feel this would both give more value to the shuriken ninjutsu over raiton as well as bringing more flavor to mug and throw.

TL; DR: Mug could steal stuff, resulting in a proc that alters your shuriken to throw something else.

So overall ninjutsu rotation would still be suiton>raiton>raiton but every 90 secs you would get a chance for mugging something nice and depending on that would change a raiton for a shuriken.
