Wut yes it does.
both kof and sfxt has comeback mechanics
Like I said, "Broken" comeback mechanics.
aka taking advantage of the opponent not playing smart, not "luck."
If you land a hit, you wouldn't do anything different if you go the hb or not. You'd still go for the maximum damage. You're taking advantage regardless of landing the hb or not.
It also goes the other way, when you get too hasty about a happy birthday and end up beating up on the assist, leaving yourself wide open to the player who fell out of it
Something that occurs a miniscule amount of times compared to the frequencies of a legitimate hb's.
SFxT does have a broken comeback mechanic. It's just broken in a good way... the way that makes it mostly useless.
Pandora is hardly broken. It's extremely, brutally, impossibly situational to make it "broken". Hence, it's just a quick final attack that could potentially KO an opponent. Feel free to correct me.
