No, this is not holding up melee, Joe will be working on melee.
As for the oh noes, it's giving strong players an advantage: the only practical application of this is to slow down a beam with your (or your buddies(!)) beam/ball, then swat the beamstruggle. A strong player would just win the ps right away or have enough ki left to teleport. A weaker player can protect hisself this way.
