Kha'zix ult revert on PBE
From PBE: Void Assault (R) Cooldown lowered from 100/90/80 to 90/80/70 Active invisibility lowered from 1.5 seconds to 1.25 seconds [Changed Effect] "Void Assault can be used again within 10 seconds of the initial use, up to 2 times total." Evolved Adaptive Cloaking [Changed Effect] "Void Assault's uses are increased to 3 within 10 seconds, and it's stealth duration in increased to 2 seconds"
In case you don't remember, Kha'zix's ultimate evolution used to be an extra charge and slightly longer duration on stealth. While his ultimate does need to have some power taken out of it, surely you remember that everyone just chooses Q > E > W when his ultimate evolution is complete crap (which the revert will be). It needs to be unique like it is currently. Not just an extended form of the exact same thing.
