@Riot any chance for other Kha'Zix changes?
The extra early sustain is good, but until it goes live we can't be sure if it is enough. There's still the big problem that his evolved R is well, garbage.
After these changes go down, if Kha is still struggling is there any chance his ultimate could get a change? Perhaps something on his isolation? As of now a very large portion of your damage is reliant on the enemy running off alone, which rarely happens late game. If we're 40 minutes into a game I can't do anything because nobody goes off alone in an unwarded jungle, and Kha'Zix gets destroyed by an upgraded sweeper or someone being within 10 meters of a minion.
Please do something about isolation, you literally nerfed his Q 3 times in one patch (4.10, removed execute, increased isolation range, lowered damage) without seeing how each would affect him. Either lower isolation back to how it was on release or give him the execute. Or do something about his pretty much useless ultimate. As of now his ultimate is pretty much 2 procs on his passive. Pretty underwhelming for an ULTIMATE ability.
