Yeah, I don't think my theory and the neutral element theory necessarily jive well with one another. The neutral element theory could be part of the whole selective breeding thing, but I feel that it makes more sense in the context of the story (Mei not having a KT, dust being the only KT we know of) for it to require all three without the relative neutrality/strength of the elements being a factor at all. After all, a "strong" element had no trouble combining with a "weak" one for the two- part advanced natures.
