Ranged Champions get too many free stats in addition to Ranged AA's.

Kiting is a broken and unfun mechanic. Why can any ranged champ perfectly kite a melee champ?

Ashe vs. Udyr is a good example of this unfun kiting.

Other ranged champions can do the same thing with red buff or frozen mallet.

Many ranged champions also have gap closers or escapes.

There is no significant penalty for being a ranged champion.

Melee champs generally have higher stats.

Higher stats don't matter if you can't use them.

Since Frozen Mallet's build path was nerfed because several Devs said "There are no situations where FM contributes to interesting game play" It follows that there is nothing interesting about being chased by a ranged champ who can constantly spam slows or stuns. Kiting is not essential to the game and should be removed.
