Playing on PS4 and I have mudra delays often, so much that even Raiton is difficult to use within one GCD and Suiton/Huton impossible. I've also had missed mudras even when they loaded meaning failed ninjutsu and from using the ninjutsu reset I got at least 1 sec delay on it.
For a job that need to exploit every bit of cooldown it's really annoying with these delays/lag
