I'm sorry, but I'm really not satisfied with the Kha'zix jungle. I do mine very differently, and I find it makes much better use of his abilities. The Route is just fine, but really, W first? His Q is an excellent nuke, take out the smaller minions first then start on the large guy now that your Q does extra damage. Take W next when you don't have a leash anymore because you'll need the sustain. I love to surprise champions by jumping over walls while they B next to a turret because they never see it coming, and he's really good for cutting off champs trying to gank through the river or just on their own farming. Build Kha'zix as a more of a glass cannon, taking a phage/frozen mallet to give you the health needed to survive, most other things nearly pure AD and lifesteal.
