Kha'Zix bug

Here to talk about this bag, his damage is lower, his basic attack is okay but taste their fear now deal very small damage even if they are isoalated. I am masteries level 5 with Kha and i know his Q dmg, it was about 1500 hp, now says same but damage i see is very weak, before i needed 2 Q to kill someone, now i need 3 or even 4 to non-hp champion, fix this bug quickly, it is bug because there was nothing about kha in patch notes.
