@Phantom

I do realize they must exist. But can you really say that someone submitting a Semblance that basically makes them a Firebender would be greeted with open arms, when Fire Dust is clearly a thing?

@Hookshot

Yes, it's been confirmed that Dust comes in four basic, core varieties, mixtures of which being what other types of Dust are formed from. On that note, who's to say that Fusion-type Dust can't be naturally occurring? Sure it's probably rarer, but minerals mixing and forming new minerals in nature is not unheard of, last I checked.
