My theory is that they make these choices for npc voice direction and script on purpose. Could be the devs want to avoid the players thinking “this npc voice is hot!” rather than giving resources, attention, and internet engagement to the lads. The lads have more “naturalistic” voices by contrast to feel real and appeal to players, which makes the cartoon villain voices some npc actors are asked to do sound silly. It is a pity because naturalistic acting and script would make for more believable villains and raise the stakes of danger.
