You're talking like a pre-patch Bane right now. Snap out of it.
Against BA, his lightning is a problem BUT he only has so many uses of it. The more meter he wastes throwing stray bolts, the better it is for you. Likewise, you don't need to respond to lightning with an attack. Your dash is one of the best and fastest recovering in the game, just prance and make him regret spending 1 bar for about 5% in chip. As far as pushblocking, yes if he has the spare meter to pushblock but then he won't have the meter to keep you out.
You see where it becomes a problem for them? They have to wager everything on if they can keep you out now, or if they aren't going to be able to. Add in armor (like on Mb venom) beat pushblock. Your f.2 covers HUGE real-estate, so don't be afraid to poke in and out with it. The best option he has is to dive away, and even then you'll be right behind him (I tested MB lightning, if you delay the armor you'll run right past the hitbox when you do pop it).
All of these things affect my character too, only my character also has the downside of massive debuffs when he gets pushed back out. You have to be aggressive and stay aggressive, and sometimes you'll want him throwing lightning, let him waste a few bolts and then charge in balls deep. You won't be sweeping the match, certainly not, however if you give up at mid-screen then you're forfeiting one of DD's best tools which is his ability to get in.
On block you have tools like b.1xx normal throw which will definitely keep them off guard, and b.1xxvenom to mix them up. You have presence after normal throw that cannot be denied in the form of MB Venom. Its like I said in the Bane v DD MU, you have to go with the tide of the match. Manage your meter better than the opponent, and don't be afraid to risk when you know you can get away with it. (and rightly so, BA has a hard time breaking open DD). Take your damage where you can get it and just try to stay ahead as much as you can. You don't always need to be in deep, and sometimes its better to let them take a shot or two at you that you know you can avoid simply to make them drain resource.
