Could we cut down on marksmen mobility please?

Marksmen like Lucian and Vayne almost have as much mobility as slippery assassins and fighters like Fiora. It just seems excessive when they can simply ignore or completely outrun everything short of a nuclear bomb.

Here's some numbers if you don't believe me.

Lunge 16 / 14 / 12 / 10 / 8 Or 8 / 7 / 6 / 5 / 4 Distortion 18 / 16 / 14 / 12 / 10 Playful Trickster 16 / 14 / 12 / 10 / 8

Arcane Shift 19 / 17.5 / 16 / 14.5 / 13 Relentless Pursuit 18 / 17 / 16 / 15 / 14 Tumble 6 / 5 / 4 / 3 / 2 Tumble Dry 10 / 8 / 6

Now the dash distances are obviously different, and the cooldown may seem a bit higher for Ezreal or Lucian, but bare in mind that marksmen now have a much easier time maxing CDR than say Fiora, Fizz, and even Leblanc.

Right now since marksmen build a lot of health and stats for survivability, it seems a tad excessive for them to dash here and there without any real take-away. Finally, marksmen are capable of kiting most every champion which invalidates their need for peel, as such they become incredibly strong one-trick ponies. I don't know about y'all, but it seems detrimental to the current state of balance in the game.
