"I know we've been thinking about a general CC reduction stat, kind of like what's on Mercury Treads right now. Not sure if that'll be in next patch, any time soon, or ever."

"If this stat does get implemented (no guarantees), it will follow the rules of boots' "UNIQUE: Enhanced Movement" stat. That is to say: only the highest will take effect. So, no stacking"

If you ask me, it seems like a great idea. Merc Treads are a must have for most champions against any sort of acceptable enemy team composition. There are tons of characters you'd like to have the attack speed boots or cool down reduction boots early game and then be able to pick up a form of CC reduction late game. I APprove.
