I could see Guile working fine if:
1. They give him a target combo that has good push back and can be done off of a st. fierce crush counter; or
2. They give him one motion special to use off of a st. fierce crush counter.
Instead of using CC to go on the offensive like the whole cast does, Guile can use it to push his opponent away and force him/her back into fireball traps. I could see it working. Not only that, but Guile is the king of exposing players with no fundamentals, lol. I need to cause chaos in SF5.
