I would like to point out to all those suggesting we can "weave" mudras during actions, it is NOT a solution. Given that you need to reapply your huton every 70 sec, and you have 3 times 20 sec CD in there, you need to input all your mudras in 10 seconds -- most likely 3 + 3 + 2 = 8 of them, 10 if using kassatsu. That means you can't wait 2 sec for each mudra.

Just put the mudras off server. Who cares if someone cheat by doing a script for instant mudra ? Its going to be a corner case and it isnt even that impactful (and way less cool). Just check the ninjutsu with whatever input you have locally used then.

Also would allow us to throw ninjutsu like cool ninjas do -- like they do it for npcs actually, and as it is done in what is, like it or not, the most popular mudra based jutsu representation, naruto.

Imagine Sasuke being like during fight :
"katon ! shlunk... goukyakou ! ... shlunk... no ! shlunk... jutsu ! ..."

No, the whole thing is done in a fucking second, its super fluid, and it rocks. Same goes for the npcs in the game. Yet whenever you are doing it, it seems like you are a 5 year old learning to do jutsus for the first time of his life. May seem minor but it really lower my pleasure of playing the class.
