Actually, I just thought of another possible reason for Mei having two advanced natures with a shared element, but no kekkei tota: the kekkei tota requires the genes for all of the two part natures that contain those three elements to work. Mei has futton and yoton, but has no genes for mokuton; so they couldn't combine into a three- part nature. As in, she can mix fire with water, and fire with earth, but she can't mix earth with water, so she can't possibly mix all three. It would make sense: we've seen all three advanced natures containing earth, wind, and fire in and near the Land of Earth, and it wouldn't be unreasonable for Mu's clan to abduct scorch and magnet users from their native lands nearby. Mokuton, meanwhile, could never be found in anyone but Hashirama, so Mei could never have a kekkei tota. And, with wind+lightning and fire+lightning still undiscovered, other kekkei tota would be nigh impossible to make, explaining why nobody elese ever succeeded in doing so.

Ahhh I see what you're getting at. That was one of the earlier theories in the thread actually. No doubt the concept of a Kekkei Tota requires some sort of neccessity. If those advanced natures in the 3rd shippuden movie wer canon, I'd say Swift and Dark would fit those respective advanced nature slots, but theres little to no evidence to support that, and they were kind of half assed anyway. AS for no one else succeeding, Mu would of had to develop the concept from something; perhaps a previous event in history. Kekkei Tota could of possibly existed at one point during Hashi's era, maybe even earlier. I mean there was like 700-800 unexplained years in the timeline between the Otsutsuki and Hashirama and Madara.
