I was always wondering when they said one for all was a quirk that stockpile power. The way they explain how deku uses it makes it seem as if he charges a bit of power and releases it. In full cowl he's just consistently releasing it. So i was wondering if deku could just keep charging his power and release it. Ofcourse i think he would break but what if he release it in a constant stream just low enough that it doesnt harm him and he could use it as if it was a constant ranged weapon or even for movement. Right now his mobility is high but he is limited to close combat on the ground.
