Khazix Buff Idea
Kha'zix doesn't need a 20 point heal buff to his W. His early clears don't make him too healthy, but it's the least frustrating thing about him. I'm proposing a buff for his evolved ult and W.
Right now his main problem is isolation. Seeing as Riot won't buff the ranges, I think that there should be another way to cause isolation. The W buff would allow that. After evolving w, hitting something with it would decrease the isolation range of the target greatly, and would stop isolation from turrets. The evolved W slow and missile width could be tuned down a little for compensation.
The ult buff would let you have a brief period after using his ult where Kha could ignore isolation. These two buffs would stop evolution paths from being fixed every game. For example, evolving your ult would give you more reliable at the cost of a larger cooldown, while the W buff would add a less reliable way to apply isolation but at a lower cool-down.
tl'dr: khazix needs buffs omg
