So I've noticed something, but I don't know if it's just me, my KB or something else. When my character is facing right (P1 position), I can input bf moves pretty much freely. This is because you don't have to even release b before hitting the rest of the buttons and you can do this even if you're very hasty with them. However, when facing left I must release b well before pressing anything else otherwise, for example, b2 will come out instead of bf2. Very annoying, and I'm not sure why is that.
Sometimes I feel that I need to even wait after releasing b before I press f... It's pretty bad.
Can anybody with KB/hibox test? Or at least compare your success inputting bf left-to-right and right-to-left?
