Signum wouldn't use Agito during a match between herself and another TSAB member unless the other member was also using a unison device or some other kind of broken power up or had a partner. That's two on one.
I don't see where they could make a season that focused on the Numbers, but I'd like to see the better ones come back as major characters. I'd like to see Hayate have a few stand out moments of badass leadership, too.>>10488299

IIRC, Nanoha mentioned that it was getting tough to take on the forwards while they were working as a team, and they're only going to get more skilled and powerful (well, maybe hunting poachers might dull Elio's and Caro's fighting skills a bit...), so I wouldn't put it past Seven Arcs to elevate them to that level sooner or later. (they were like A- ranked at the end of StrikerS, right?)
