just saw an episode today where vegeta blocked a beam.. it looked like he used a lot of power to block the beam, it made quite a big explosion too. So here is my suggestion, if they could make it like so that you were able to put some power in your block.. dunno how.. maby holding the blockbutton and then press and holding fire to "charge" your block.. then you were able to block a heavy attack.. then if you dident put enough power in your block, or the beam just it too powerfull it would lead to a blockstruggle as it is now. so.. what do you think of my suggestion?!?
