Names are simply better than “level 1 fighter” “level 2 fighter”
When players start the game, the best they can capture is probably just a level 1 fighter. Give them an option to name him Bob! And who knows, name the dancer with his ex’s name, and name the cook Gordon?
Costomizable naming is rather simple but gives way more immersion to the game.
Also, since named thralls are preset, I heard there are clans that have 3 freya. In this case, the named thrall lost the unique feeling, and it’s probably just better off as “lv4 fighter”. Customize name can give the clans a way to change the name of duplica as well
