Khazix needs a slight buff to his survival or clear time in the jungle. The W nerf (8 sec cd to 10 sec) was unnecessary. The 2 seconds actually hurt him more than you might think. Often, you can die to creeps just 1 or 2 secs before the w is up. I havn't played him for months, I used to and just noticed how low his win rate is (12th lowest) and how the w nerf harmed his jungling and decided to post.
