actually there are teasings and rumors here and there that each of the Scions is an avatar of the gods, or at least DO have some sort of special power. Minfilia's powers are just different from the others. AFAIK they still can't be tempered, so there IS still something special about them all.
And since we only had six or seven of the twelve avatars at the battle of carteneau flats, that's why the seal on Bahamut failed.
The numbers add up too:
Minfilia
You
Y'shtola
Thancred
Yda
Papalymo
Moenbryda
Louisoix
Urianger
Alphinaud
Alisaie
Yugiri

Of course this is all speculation. For all we know there could be another since the status of some on there is questionable (there is an actual total of 16 named members, though Hoary Boulder, Coultenat, F'lhammin, and Tataru have more of a "peanut gallery" vibe to them, and we're still not sure how Krile fits into all this.)
I only list Yugiri, btw, since the Scions seem to have a key member of each race as a representative with very little or no overlap, with about 2 of each race if you count Alphinaud and Alisaie as one person for that purpose, what with being twins and probably representations of Nald and Thal.
