I believe that there are mods attempting to fix SI ability to scratch when staggered which especially pronounced in expert mode, why not implement it in the coop servers?
i kinda wish this was a thing but at the same time i'd also like the jockey hitbox issue (it usually being in front of the SI instead of where the model actually is) fixed also, but there doesnt seem to be any fixes currently available unfortunately as far as im aware. but i do also wish the stagger scratch would be fixed tho
