Last I heard, it was dismissed by the devs saying there was little more they could do to fix the problem. Even at 150 ping, mudra lag can sometimes be unbearable.

"Jin - Chi - Ten - Huto-! Wait, why is it showing Katon? Ok, guess I'll just throw down Doton and cry without Huton for 20 seconds."

Or my favourite: Suiton animation goes off, then game decides it never actually landed and switches to bunny after I use my next GCD.
