I made a point about it on my post too,
I totally agree the knockdowns are too punishing, you’re basically dead. I think that’s not necessarily a bad thing if the game had like a very telegraphed attack and you must dodge once in a blue moon.
However the amount of moves that knock you down are thrown at you constantly and at speeds that are not super generous to the player.
I made a suggestion to fix this issue, but yeah I think that knockdowns need to be tuned down.
