Just a thought on improving the game experience (new game mechanic)

i just had a thought why not all knockback towards the walls not count as a stun? i mean it wouldn't make any sense for you to be landing softly on the summoner rift's walls unless they're all made out of cushion...

there should be a mechanic where if you are knocked back at certain speed or just knocked back in general towards the wall, the champion takes certain wall hit damage and stun. this would make things so much more interesting although it would mean it being a indirect buff to all the champions with knockback and thus making players only resort to playing those champions.

Just a thought
