Knockdowns are very powerful in SL2, but I would also they're critical to exist to reasonably handle hyper damage threats and healer threats in teamfights. Still it is undeniable that denying your opponents up to 3m multiple times a fight, and that's mainly the abuse case, multiple times a fight. The Quadrapedal is good at mitigating the effects of KD but I don't think it suits everyone, there should be a more generic controlling option too.

Silence in a sense is a very similar status where you are forced to use momentum to need to deal with it generally, but Heron Feather at least mitigates your opponent's choices in the matter, an item that is 1:1 heron feather's effect would not work for KD however I think, so I have another idea.

I believe there should be an item, a shoe slot, an accessory or whatever have you that increases the immunity you gain from being cured of KD by +1 round, this would make it so that you aren't denied 3m constantly, as that is most of the frustration of KD is when it's spammed from the likes of Demon Hunter or Paragi Shuriken for the most part.

In Summary: There should be an item that gives +1 round of KD immunity, likely on an accessory or any other fitting slot.
