Too big to fail

So I'm re-watching the Rep. debate and the subject of Dodd-Frank and Too Big to Fail has come up. 

While I am supportive of Dodd-Frank, the argument that the big banks have the lawyers to get around it while the small banks do not is somewhat compelling, especially when coupled with the claim that JP Morgan Chase has grown 40% since the financial crisis.

Is the law of unintended consequences rearing it's head here? 

our hope is that the banking reserve requirements provide sufficient margin to protect them from collapse.

Can anyone cite before-and-after requirements? Or do I need to be un-lazy and Google it?
