Yep, as Lexx said.Also, imagine you "buy" a mercenary at some pub or recruitment center or so. Wouldn't it be stupid if you can give him a name? As if he didn't had a name in its former life, just waited his whole lifetime till you (the player) appears who can give him a name? So if a merc is called "Frank" it should stay "Frank".
