Kha'zix isolation is not working

Hello guys im new to the forums and i just wanted to say that kha'zix since rework has been suffering from this bug and riot seem to ignore this i think this is a very serious issue and if their is no fix then they need to give us old kha'zix or rework him again so i don't need to say much i will just send a video but keep in mind in this video it doesn't show all the champions who can deny kha isolation there is much much more and i don't know the reason because kha'zix before rework didn't had this issue so i doubt it for example singed q they say its coded as minions if that is correct then why kha before rework could isolate singed and now can't , so ye anyways thanks guys and sorry for bad english hopefully riot fix this problem asap because it been since rework of the kha'zix
