As I said it's something that will never be fully solved, and has been an overarching theme with each and every season. Melee champions used to fully outclass ranged, and right now the ball is on the ranged side of the court.
If Riot things things are close enough the balance team might be trying to keep things as is, with ranged outclassing melee. Riot hasn't said this is the case, and so we will likely see them continue to try and even things out. We won't get quick fixes like the assassins are getting, we're dealing with something that effects every single champion in the game.
This isn't about particular champions, or even a particular role. This is ranged vs melee, and if it's even possible to find a perfect balance it will likely take years to find, not counting the years that have already been spent.
