More Nasus Bugs

I'm not sure if this is related to the AA bug that is currently happening with Nasus but, the problem extends further than just the slow motion auto canceling. Even if nasus animation goes off if he is stunned or displaced during this animation such as fighting against riven w, or third q proc, the damage completely gets negated and your siphoning strike doesn't apply whatsoever. So if done correctly by a riven player she can stop you from casting your q animation off for a good 4 seconds then dash away with her e wait for cooldowns and complete the process over without taking ANY damage not even one auto attack, while you just take continuous damage. I've checked it with other champs like darius's W, blitzcrank's E, Fioras's E, Garen's Q and even Jax's W and their damage still applies once their animation is already in motion. This should be addressed soon because it's a real hindrance to play with.
