Client Side Mudras

[Kiara1]

Everything done client side can be manipulated (edited/hacked).
If Mudras were done client-side, it would be possible to create a program that tells the server "Yeah, I did X combo" at every moment, without having actually done so. This is why very few things are actually done client-side.

I actually dont see how this is a problem if the ninjutsu (i think thats what the skill is called) isn't client side.
Its not like you can do anything with mudras outside of ninjutsu anyway so what is the point of hacking it.

Am I missing sometihng?
