Kha'Zix R

What if instead his R actually gave something when you used it, other than mediocre stealth and a passive proc. For example, when evolved the next passive proc after leaving stealth does a little more damage or more slow, or even maybe gives a debuff that allows his Q to do more damage to that target.

This way once he hits 16 he actually gets a power spike like nearly every other champion. Right now his W is only really good for vision; poke isn't exactly desirable on an all-in assassin, and his R is just bad when compared to what it used to do. Obviously we can't go back to old evolved R, 50% damage reduction is pretty dumb on an assassin.

An ammo system wouldn't be awful, but that still doesn't fix the major problem of that stealth being horrible. I have probably died in my stealth more than I have successfully escaped (doesn't help that using disables stealth). I use his ult offensively more often than not simple for the move speed in a chase or the passive proc. His ultimate's utility doesn't even come from the stealth it gives, but the passive proc you get.

Another plausible change would be to have evolved R change isolation some how. Whether it has to do with passively decreasing isolation range or decreasing on using the ult, but that still is attributing to his Q more than his R.

All things considered though, Kha'Zix's evolved R is pretty bad. At least his W gives vision, and his Q and E are core since they're his damage and mobility. I'm not saying it should be a priority balance change, seeing as how PLENTY of other champions are in worse shape, but if Riot does decide to give him another little love tap it should definitely directed at his R.
