Dust has elemental effects. It in no way does what you want it to do, if you have watched the show or read the wiki page.

A semblance that provides buffs would inherently be less beneficial than several methods to reduce several enemies' effectiveness such as denying areas or stunning them, which would not neccesitate aura. Unless that support semblance was significantly strong enough to outstrip the effectiveness of area denial in combination with a utility semblance like Weiss's regular glyphs that allow her to reposition her allies, or a drone semblance that can give valuable information about enemy locations, then it would not be necessary. If that were the case, then it would be op by nature.

TLDR: I prefer more utility based semblances over support based ones.
