My wind guy is likely going to be split into around 3 different characters based on different power ideas I came up with. This one technique sounds like something perfect for a bad guy, but I imagined it where he had a load of shrapnel that pours out and is blown around to shred enemies to pieces. Sounds perfect for collateral damage, which is why I'd prefer just to give it to a bad guy wind user. I don't remember anyone doing this for a wind user yet.
