One way that the creators of SSF4 can do to improve the game is from switching from holding back to block to having a block button to block. Like I think the whole concept is stupid. A block button would make a lot more sense than holding back.
For example alot of people probably already noticed, but theres this weird glitch where if someone were to perform a jump attack a little past your head, if you tried blocking that by holding back, you would get hit!!! This happens because once they switch sides while in mid air, your “block” would switch into you walking right into their attack. This is complete nonsense and I find it to be rather unfair. If there was my suggested block button, you would not have to worry about this glitch. Hopefully capcom takes out this weird glitch or they put a block button in the next game.
