Before the armor buff, I would use b32f2 or a hard knockdown ender to get ready for an armor break with ninjutsu , but now that many characters have 2 hit armor, there's no point in hard knockdown except for against a few characters like Predator whose Scimitar stab can be broken or Cassie Cage who's only armor outside of Brawler was glow kick which can be broken. only useful in very few matchups that restand is a must
