User blog comment:Ozuar/Kha'Zix - My Conundrum/@comment-4290320-20130410180504

I've played Kha'Zix and here's how I max and evolve my abilities:

Q: Max it first for quick burst damage, evolve it last because the bonuses aren't THAT good.

W: Max it second, evolve it second. Max it first if you get into many teamfights.

E: Max it last, evolve it first. Evolving it will save you from many neardeath situations.

R: I rarely evolve it, except if the enemy team has a lot of sight wards, enemy champs are camping at their turrets, etc.
