That is why I use EX aura if you go for the reset. The reset is not B12 xx aura xx B12. its the part where you B12 ~ B2. Its called a reset bc it does not combo so it resets the damage counter. aura into B12 is a combo. They connect.
I see. Will test it out. Sounds like you're trying to say that you need to do the B12, and then the B2. And judging by what you said, I'd assume that ours opponents would have to block high. Have you thought of doing the BnB options there?
Instead of doing the B2, how about you do the following:
B33xxFrost Bomb, RUN, B12xxIceball, Aura, NJP, B12xxBurst. Around 35%.
F33xxIcy Slide (only if you have Aura ON), SS (means "Switching Sides"), Aura, NJP, B12xxBurst.
123xxIcy Slide (only if you have Aura ON), SS, Aura, NJP, B12xxBurst.
If you do the B2, then do:
B2, RUN, F42xxIcy Slide (only if you have Aura ON), SS, Aura, NJP, B12xxBurst.
Since the B12 is a pressuring combo, you should run towards your opponent, while he's stunned, to close the distance to do the BnB options.
And since B2 is a late starting one, I imagine that it would need a strict timing to make it able after the B12. Will look into it once I hit the PS4 again.
