@Meddler/BalanceTeam Questions About Our Favorite Bug and Assassins

What are your (the balance team) thoughts on Kha'Zix? I currently think he is in a good spot right now but what irks me is his evolution choice. You always evolve Q first for a faster clear and more damage but then the only other note worthy evolution is his e. It saddens me that his other evolutions are not as satisfying to use as the others (his r evo is close tho). Also you guys stated that assassins might get a gameplay update near the fall, would Kha'Zix be down for a rework, like you said is highly likely for Rengar? It'd be great to also hear your follow up on a thread i made that you commented on (http://boards.na.leagueoflegends.com/en/c/gameplay-balance/iygfWEQv-meddler-what-do-you-have-planned-for-khazix ). Thanks alot if you respond.

Edit: Thanks for downvote with no explaination.
