What if the evolution of Kha'ZIx's Q reduced isolation range by 100?

I still think that glass cannon kha'zix has more difficulty than any other assassin making picks because of how isolation works atm, and I think any sort of reduction in the currently brutal isolation range would help him out immensely. I remember Xelnath saying specifically that isolation ranges on Kha'ZIx's Q feel best at 500 since it LOOKS like you're isolated and not just outside of an arbitrary unit limit, but at the same time, I think kha'zix should be rewarded for tailoring his kit towards isolation in more ways than just straight up damage. I'm suggesting just a small range buff for kha'zix when he chooses to get his Q evolution, as it gives him a tiny bit more leniancy when it comes to taking out HVTs.
