I'm not sure if "odd numbers" is an issue of any kind when it comes to the number of companions, but I'm kinda hoping for some chance of some late addition to the cast.
It would be a a bit of bummer if we are locked with a range of companions that are all pciked from EA/Act 1 out of the first NPCs with more than two lines we met on EA, only because a bunch of weirdos immediately started simping HARD for them.
And frankly while the community put its best effort in making him come off as almost insufferable I don't even dislike Halsin as a first impression.
Minthara on the other hand is someone I can't fucking stand, so the hope would be for some better options down the line.
On the good news: no Alfira.
I meant that if they are up to 10 companions and they are going to announce another one it lands them at 11. There are 12 classes in the game and if they add one more they would be able to have a companion for every class.
I know people are thinking there might be 'two druids' or something like that, but it wouldn't shock me if Larian throws a curveball or two with the companions and what their class will be.
Could be wrong though! Maybe it's just one more and there will be an overlap with having multiple druids or something, but no companion offerings of other classes. Or maybe the non-origins will be able to change their class or something... or maybe all of them will be able to?
