We need to talk about mobility and melee/range balancing

Riot has stated that they are aware of and trying to work on mobility creep. They also have made statements about trying to improve the interactions between melees and ranged champions, particularly in solo lanes.

But, in the mean time, they keep releasing champions who are hyper mobile, or practically immune to melees, or both.

Look at the recently released champions:

-Gnar: large dash, a ranged auto attack, and an infinite slow on his Q. Regardless of how many times Riot nerfs his base damages, a well-played mini gnar is always going to be virtually immune to dashless melees

-Kalista: infinite kiting. Pretty much seems like Ashe 2.0: she has a team utility, she has an initiation ult, and she has kiting. Only, her kiting is way, way better than Ashe's. Pretty much immune to dashless melees

-Azir: I don't see him being brought up too much in these discussions, which surprises me. Because he's absurdly punishing to play against as a melee (in team fights and in lane). He's got over 1000 range on his main damage source, and a slow, and a relatively low cooldown dash. And if you somehow get to him through all that, he has an ult that not only knocks you back, but completely blocks the path unless you have flash up.

-Yasuo: not the worst offender, as he's melee, and his mobility is tied to having nearby minions or champions to dash to. But still hyper mobile by the standards of older champions. And still surprisingly good at disengaging with his tornado, which is impossible to dodge at low ranges.

I don't want this to be a Riot hate fest. I've played since S1, and I've always been impressed by how approachable Riot is, and how willing they are to discuss and try to fix problems with their game. I trust Riot--I trust that the people designing champions and making macro level design decisions understand the game better than I do.

I just want reassurance that something is going to be done about this. It's at a point where it's perfectly normal for every champion in a game to have at least one dash. Every time riot releases another champion like Azir or Kalista or Gnar or Zed, dashless melees take another step towards complete irrelevance. And you cannot solve the problem by simply buffing dashless melees, or giving them dashes.

How is anyone supposed to play a champion like Volibear in the current meta? It would take a complete rework for him to be playable against modern comps. How is anyone even supposed to play some of the melees that, in earlier seasons, were actually considered hard to get away from, like Shyvana? I've been playing a fair amount of Hecarim recently in normals. Hec is in no way shape or form low mobility when compared to the S1/S2 champions he was released after. But it's getting to a point where even his mobility isn't enough to allow him to stick to recent champs.
