Hello guys.Through a day of fucking around in Extend training mode, I've come to the conclusion that 6D is the best move ever. It has the biggest hitbox in the world, I swear to God.
Also, j.C cross-up works better the wider the character is from the top of their body. It's really easy on Bang, but tough on Hakumen who only gets wider at the bottom of his hitbox, thus requiring you to be really deep in with the j.C (making it kinda pointless).
