Riot, when can we expect a Kha'zix update?
This champion has been hovering just below viability now since the beginning of season 5. He was adjusted so that his laning phase became much more difficult with the isolation changes and the mechanic in general being difficult to take advantage of. And when you are able to take advantage of isolation, it does not pay off nearly enough until much later in the game. The scaling on his evolved Q is very good, but the base provides very little advantage for a champion that relies so heavily on isolating a target.
All I ask is that you consider some alternative ways of allowing the bug to lane and/or jungle more effectively so that he can provide a significant threat early and mid game if played appropriately, while not losing his explosive charm late game when team-fights roll around.
I also invite the community to provide any suggestions that might play into his situational playstyle.
