That shit is silly that you have to repush back to get b2 to come out and if you do b2,1, F2 too fast rings come out.At least its not just me. I've started going to the lab with Sonya next (even though I still have a lot to learn about Kitty), and this is by far the toughest thing for me. I can get it so if i just do MS, B2 I can do it consistently, but as soon as I add the 114 before it, it throws me off and that damn shoulder charge comes out. Really wish you could just hold back instead of letting it go and hitting again.
