Mobility counter
So I recently started playing Smite and I noticed something that I thought would be really good for League. Just to clarify I am not saying Smite is better, it has its own issues, its just where I got the idea.
Some Gods have abilities that would only silence mobility spells. The player could still move, AA, and cast all other abilities not associated with mobility. Now, we've already seen this with the new poppy but I think similar ideas could be used to buff or nerf existing champions without breaking them.
For example
could be nurfed so that his Q only stops mobility spells. This would still allow for him to reliably deal damage with his spin but allow counter play to his opponents. Or if we decide
needed a buff this effect could be added to one of his spells allowing him more peel and to land his ult without burning flash every time.
On top of it being another nurf/buff lever, having a few champs being retrofitted with this effect would allow for more counter play against the ever popular mobile heavy champs without just resorting to heavier forms CC.
