I started a thread on corners a couple of years ago and got mocked for it but it's the one area of the game I'd like to see the next big rule change. You have no hope of scoring from a corner in general, all the evidence shows that. in my opinion a corner does not represent a fair trade off for the attacking intent that went into getting it ( which is why Barca just play it back). I'd love to see some new things, penalty corner if the ball goes behind the 18 yard box? Reduced defenders? I don't know but at the moment they are a waste of time.
