So what did everyone think about the amount of ships at frontier day? Was it enough, not enough, or just enough? Just saw this from the production designer
Worf does mention all of Starfleet, but Shaw says most. So they do make mention of the amount in the show. We also see on the screens ships by name, this seems a little smaller than I would think for Starfleet. So I would say not enough.
If Picard gets help from the rest of the federation he could outnumber these ships with just a couple from some powerful allies. He could also just reach out to anyone Federation or non Federaton, since the borg would eventually come for them next.
I don't know the current state of the big factions in this century, but Picard could put out a general distress signal. He could gather the Klingons, Cardassians, Andorians to name a few.There are tons of enemy of the borg. Picard just needs to put out a call to muster a fleet.
But if they keep it just a small group for budgetary reasons, I would hope they at least have Janeway show up and we see Voyager, and the D crew fight these borg. If we see the D, Voyager, and the Defiant ships flying together against these it will be a good moment. Doesn't matter who flies them, I would just like to see it. They could be remotely flown. The easiest thing for the show to do that is very cheap is just have Jack or some kind of backfire of this link to incapacitate the borg. Not very thrilling, but very easy to film.
