Fine, Shale, Aveline, and Sigrun can come back as well, those were just the names off the top of my head.
But based on your tone, nothing so say would appease you
It's just really suspect that the characters you can't see being interesting are almost all women, and the characters you want to replace them with (despite the fact that we've had ample opportunity to explore a couple of their character arcs) are all men. You might not realize it, but that's exactly the sort of thinking that leads to women being relegated to supporting roles in, like, everything.
Which is why it struck a nerve.
As for LIs, here's to hoping for the rest to be revealed at GaymerX. I have a feeling we only learned about Josephine because her writer volunteered the info herself. I'm also crossing my fingers that the remaining three LIs are all companions, and that there are a few flings that don't count towards the total. I don't think there's any way to divvy up what's left in a way that's remotely fair to everyone, since there is no way that a non-companion/adviser can be as deep as the main ones. At the very least, I'd think one is an un-gated bi male, otherwise gay male players might only have one LI in some playthroughs, and it seems like that's exactly the sort of thing they wanted to avoid.
