Thanks guys! I'll incorporate this info next time I edit the OP.

I might start a database of every item that can be dropped by a piece of dungeon (or turn-in) gear... I just haven't bothered to keep track of non-rare/unique items, but honestly, it would be nice to know when deciding if I'm going to desynth a random dungeon drop or turn it in for seals (especially items i60 and below, which can't yield BC3s).
