This entire blog post is about you crying over a champ that was blatantly OP, and a low-risk high-reward one at that.

Kha'zix was nerfed not only because of his damage, but the fact that he has some of the strongest mechanics in the game:

Stealth, damage reduction, %hp (and exectue at that), mobility, constant CC, and resets.

RESETS

If you are stupid enough to go and try to 100-0 someone as ANY reset champion while you aren't like 20/2, then there is a massive problem there.

Kha has extremely low cooldowns, and the only significant one has a reset, which is why if he has enough damage, then he can instantly kill multiple people because he has a high range jump that resets on kills.

The only change he needs is to reduce the isolation range.
