User blog comment:JBox2D/Yasuo, Ashe, the League of Mobility, and everything else that I think should be done/@comment-24511759-20140206060438

You make some interesting points, but I'm going to focus on your first proposed change to Frost Shot. One of those other mobas (Smite) has a mechanic similar to what you proposed. It's called cripple, and it prevents the target from using any movement abilities (including blinks, jumps, dashes, and knockbacks like caits e). With that said, it isn't applied as an on-hit effect in smite. Its usually reserved for single target abilities and some aoe ultimates. Ashe would not be the type of character to put it on, as Frost Shot would not only permaslow, but also permacripple. But I do believe it has a place in LoL, for instance Karma's w could use cripple to great effect. However, it seems like it would be extremely hard to balance, and adding a new mechanic into the game 5 years in seems a bit silly. Also, I think that flash should be exempt from cripple, but wether or not other blinks (I'm looking at you, Ezreal) should be excluded would be difficult to decide.
