some thoughts:
throwing dp is a very bad idea while bang is in FRKZ unless your SURE beyond a shadow of a doubt, because if you wiff or even get blocked you just lost the game. you can't ib 5A and grab before 2A unless the bang player decides to wait a while. 2D on wakeup for bang is terrible, if your ever in a blockstring and you see bang activate a drive, then chain into a low attack and you'll win. if you can get a bang player to 2D your ice sword from full screen, thats great because now you can throw a low to hit him out or just DP if you don't think you can react.
drives are almost always punishable if you know what to do, 2D 5D both lose to lows, 6D has full body autoguard but after you autoguard he can be poked out easily.
