Would diminishing returns on CC be good or bad for the game?

Simple question - should CC in League of Legends have diminishing returns?

There are a few ways in which this could be implemented, and a couple of important things to think about.

• Similar CCs (Knock Ups and Stuns) share a DR (potentially as well as silences/roots DRing if you're on stun DR)

• Only CCs with the same names DR (Stuns and Knock-Ups don't DR together)

• All CC diminishes together. (Roots and silences would DR together

• Would slows DR?

• How much would CC DR?

• Would some "micro CCs" (very short duration CCs) not DR, or apply DR at reduced rate? Would 2 micro CCs give 1 stage of DR?

Most importantly, would this improve or reduce the health of this game? This game is designed without these systems in place, and many champion's kits would become much, much worse or much much better as a result of these changes. Justabout every modern tank, as well as many melee carries would need significant changes. Imagine how overbearing champions like Shyvanna would become when this patch was first released? Just about every champion without CC would probably need to eat the nerf bat (since CC-oriented champions were being nerfed), and such large systemic changes would create some pretty horrible balance for a while. Definitely changes for a pre-season.
