Ahhh, there goes my 'theory' then. Unless its a by-product of time, or Sazed's merger/meddling. If he has 'merged' the Shards somehow, then it'd be easier to justify the splitting of sDNA just as the other Shards seem to have split naturally into a set of powers. Maybe that's what you get when you shatter a Shard, a set of 'natural' powers.
Back to the Shard-table, being that each Shard is part of the whole of Adonalsium, maybe each Shard isn't wholly in one part of the table (explaining their temporal-like abilities to read the future).
So Adonalsium shatters into 16 pieces, each 'different' in some way to the others; some (like Ruin/Preservation) are polar opposites, others kinda not so much (Devotion and Unity? Cultivation) It seems quite arbitrary, so it's either 'natural' in that it split in any old way, or its 'unnatural' in that it didnt split into things that dont polarize well. Like, this thing was GOD, which by my definition would mean he was EVERYTHING, but where's Apathy/Carefree/Null&Void, where are the guys that are not extreme. Maybe that absence nulls my No Polarized Shards proposition, since they are all extreme.
Hmmm, I've run out now... *get's his coat*
