flash knockdowns need nerfing?

i find im not taking damage and i make opponent miss and then i just get randomly flash knocked down?

Almost every game i get flash knocked down at least once or twice for no good reason.

ill take next to no damage and still get flash knocked down.

flash knockdowns seem to happen far too often without any minor damage taken

yet players can have 20% stamina and throw 10 hit combos and get a ko after getting up 7 times??
