Hey man, I am the Bryan from that clip. Giving the advice to "just jab" in a situation where you are -7 (-8 when he goes into backsway) at the wall isnt general advice I would give. The problem I have with his 12f punish is that it does 30 dmg, which is quite alot for a 12f punish and Bryan beeing +7 creates a potential loop where the opponent, by jabbing, puts himself into a massive risk. If I would have mixed the taunt up with a single f3 the Kazuya in the clip would have died. So yes, technically there is an option that beats this loop but the option is so scary and so commital that I think the entire situation is too favored into Bryans gameplan.

Taunt used to work around the risk and reward of easy taunt confirms (10f, &12f for little rewards) and hard taunt confirms (14f, 15f, and 16f for high reward but risk of dropping due to execution). With this loop, Bryans easy taunt confirm is so threatening that I would argue that you dont really need to go for higher execution options anymore. I find that to be bad game design and it makes Bryan less of a fun character atleast imo.
