Shuriken launcher gets out of sync when firing constantly

If I'm host, this is not an issue at all. Any time I'm not host, this happens, even if the lag is minimal.

If I launch wave-after-wave of shurikens without letting up on the trigger, the time between the character's animation and when the shurikens start flying out becomes longer and longer until the two are completely out of sync. If I take a break for a second, it catches up.

It kind of seems like rate-of-fire endorsements only change the character animation, and not how fast the shurikens actually fly out.

Nah it's just that they are pretty fast by default, start a private game and test no ROF and Gold ROF, you will see the difference if you just watch the clip.

As I said, I know it's not a problem if I'm hosting.
