A suggestion to buff Kha'Zix a bit

I think we can all agree that is in a relatively weak spot right now. Specifically if you compare him to how he was about a year ago, you know, when he was actually broken. Now he is so easily countered (ult almost useless other than passive procs and stalling if enemy doesn't know how to pink ward; small isolation range; towers stop isolation) and has a hard time doing what he was designed to do; assassinate people.

Kha'Zix is supposed to be highly adaptable, and every game it's the same thing with evolving, Q into E and then the last one doesn't matter because neither are great. Small suggestion would be:

A) Revert the nerf to isolation, but towers still count as allies for isolation targets. B) Towers don't count as allies C) Isolation range goes down with points in Q. Level 1 isolation range would be a bit larger than now, the 2 just a tad bit bigger, 3 the same as now, 4 slightly smaller, and 5 being smaller than currently. D) Give Q the execute back. Hey, if Lee has his, Kha should get his also. As matter of fact while we're talking about this might as well bring up .

Just some thoughts to throw around to make him a bit stronger. Seeing as how his Q is his bread and butter right now figure if we're considering buffing anything it should probably be that.

EDIT: Just remember, how about his Evolved R protects him from True Vision. Although not sure how that would work, considering True vision is meant for stealth but anti-true vision stealth would probably break the game.
