I agree with DangerousThing that firebenders should really have Create (Fire). It just makes sense for them, and a good advantage to buy in lieu of Special Background (Bender). Destroy is unnecessary, imo, since since according to Powers what you create is unstable and disappears quickly anyway (which is what you see in the show; fire is created then dissipates).

In the show some benders are clearly more differentiated than others. It's mentioned once that something like 1 in 100 earthbenders can move metal, and lightning bending is also something master firebenders can do. That's why I tend to prefer buying separate abilities with the exception of perks/cantrips.
