Hey, it looks like you're suggesting they make certain unique spawns recruitable as companions, which does make sense -- I've often wished to have an extra elf or two. But I think what the devs are going to respond is that there are only so many companions they can add before the game no longer likes it, or that unique spawns would be too strong to have as companions, both of which make sense to me.
I'm not a regular poster here, but thanks for trying to use google translate -- I'm sure there are a plethora of assholes who would love to call you out for not knowing english perfectly, but Mount and Blade isn't an Anglosphere game!
