The issue is usually cost vs benefit when it comes to voice acting protagonists.
Witcher and ME that’s easier because you have a set character. You play Geralt / Sheppard and thus how they appear and sound is pre-defined.
In a Game like this where you pick your character, would you be happy with just 1 voice option for male and one for female no matter your race etc?
I would be ok with it but others might not and voice acting dialogue is usually a costly affair.
