since ki blast is such a minor attack it shouldnt be a weapon selection, there should be a seperate button for it. so instead of having to break a target lock to ki blob someone u can press g for example and it would execute the ki shot. this would help incorperate some energy use in melee. as for vegetas super ki shot keep it the way it is and more damaging. so vegeta has the normal ki blast on g and the mad blast as a weapon selection. cuz in the show u never see them really pause to shoot a ki ball at someone, but when they shoot a beam its more complicated then a ball and they pause for a moment. and since the team cant really make vegeta fire more ki shots like the show, they should do more damage, or make a special ki blob for vegeta so its is more damaging.
