I just saw the clip of beta1.1 and I have a suggestion about beam jumping. Look, in all the dbz episodes, when people did something like that, they didn't just instantly start to go stright back up in the air. For an example: when trunks and goten were fighting in the world marshall arts tourney. Goten beam pushed himself from a was to be a smashing collision to the ground. But, he did not do it instantly. I just think that it should take a moment or two before it starts to propell you up again. And if you don't have enough power or you don't do it soon enough, you'll hit the ground anyway, regardless if your firing a beam at the ground or walls
