A [relatively] small buff to Kha'Zix's R that would greatly improve him.

What if with evolved R, whenever he casted his ultimate, the next Q within 5 seconds would be guaranteed full damage despite actual isolation. This would not buff his 1v1 status, but it would at least allow him the liberty of not losing 90% of his damage from one minion.

That's it. He doesn't need anything else. Honestly he is already my favorite champion by a long shot, but this would make him so much more fun to play. There's nothing more irritating than someone standing next to a tower, minion, ally, or even their pet and magically you go from fed assassin to adorable puppy at the mall.

Thematically, this would make sense. Before, his R reduced his damage. This allowed him to fight in teamfights and avoid damage. Riot decided (along with 99% of the community) that 50% reduced damage on an assassin is stupid, so it got taken out. However in that same patch Kha'Zix also has his Q massively nerfed, with both the isolation range increased and the execute on evolved Q removed. But back to the original "makes him not garbage in fights" theme, this new addition to his R would be perfect. Additionally, it actually makes more sense than the old damage reduction. When someone, especially an assassin, your first though is "shit he's gonna kill me." This ideal is also supported by the fact that he gets a passive proc, which not only gives a small amount of damage but a decent slow delivered by a melee attack. Someone attack you in melee form doesn't exactly seem like running away from you.

This change wouldn't even over shadow other evolutions. His Q and E are still necessary at level 11, and his W would still be better for poke based teams or if in desperate need for vision. At the very least this will give him a final powerspike at level 16, which every champion is supposed to have, seeing as how it is the final step in evolving their ultimate ability. Kha'Zix just kind of gives a 3rd use of invis.
