The hireling system is just crap in it's current implementation, it just feels tacked on.
Hiring adventurers should be possible from every hub location and they need to be fully customizable, including name, race and background. If players want to make a party of 4 dwarf fighters or whatever, let us do it.
The entire system feels puzzlingly pointless, since it's not even remotely adequate at addressing the request to have "a custom party from the start", but the weirdest thing is that it doesn't even come with the benefit of twelve particularly well-curated characters in terms of aesthetic.
They all seem rejects of the "random button" being spammed during the character creation and a few of them feel almost specifically designed to troll the player.
