I'm speculating here, but it seems this particular Sorcerer may also be a main nautiloid-type character, available for selection in the Camp.
I sorely wish that more companion options be added, though I agree with other posters that it probably won't happen yet.
So far, selecting 3 of the 5 available companions yields 10 total options. That may seem like a lot, but if you've tried every class and switched up the party every time, you've gone through 7 of those companion options. And it's not like swapping one companion for another makes a ton of gameplay difference.
I assume that's a major factor in the burnout the OP has been experiencing.
