I'm using 2h weapons, and unlocked all the cross-weapon combos. The shuriken and shuriken storm with 2h, have absolutely no projectile animations. I do the move, but ...nothing is thrown. I looked at just the martial arts version, and it looks very cool, throw all kinda stuff, it's awesome. However, nothing with 2h. I have tried swapping weapons, swapping the look of my mastery weapons, nothing seems to make me throw anything. Playing on PC if it helps.
