R Change for Kha'zix: Ammo System
People who want a backstory start here: I think we can agree that everyone's favorite bug isn't doing too hot right now. The Tank Meta isn't doing him any favors and while the recent healing Buff to his W made surviving the Jungle a bit better, he's still a bit on the weak side. That being said, I feel like Kha'zix's current play style is actually quite good. He is rewarded for striking at the right time and punished if he gets impatient. There is one part of his Kit however that I feel is just... there. His Ultimate is a bit underwhelming to say the least. Now don't get me wrong, it's useful. It gives Kha'zix the utility he needs to stick to his enemies and/or pull off some fancy jukes if need be. The issue is that the 15 second time limit feels constraining, especially when you evolve it and the periods of stealth+delay start to build up.
Lazy Schmucks start here: What I suggest is that instead of having a normal Ult cooldown, Void Assault should be given an Ammo System like Akali's Shadow Dance (minus the reset on kill). Each stack takes ~25 seconds to charge and he can naturally store 3 charges. When you evolve it he can instead store 4. The idea is that now he doesn't need to worry about the 15 second limit and can use his Ults more freely. If he blows all 3 really quick in a fight he pays for it by having to wait a full 25 seconds just to use ONE cast. This change will hopefully allow Kha'zix players to find new and inventive ways to use that 1(2) seconds of invisibility.
What do you guys think?
Edit: 4 charges on the evolution seems a bit too much now that I think about it.
