-Against 5B: IB it, hit 2A. 5B > 2B is tight, 5B > 2C is tight. 5B > 5C, 5B > 6A, you will 2A and get a CH.
bang's 5B is his only late chainable normal.
i USUALLY will late chain into 2B, so its not a great idea to mash 2A after it
(most autopilot bang players wont :3)
meterless oki is super effective on bang, i would personally recommend always going for it unless you want to kill with daisharin + kokushi.
the meter you save could be use for really cool rcs
