I actually like the unvoiced main character because it means we can have more dialogue options/opportunity for role playing. Example: Dragon Age: Origins versus Dragon Age: Inquisition. In DA:O your main character could be whoever you wanted them to be and you almost always had a ton of dialogue options to fit the mood and personality of the character you created. In Inquisition, the character was voiced but you generally only got 2-4 options, and sometimes the voicing of those options was the same line with one element changed. That said, I liked Inquisition's main character, but it was Bioware's character--not mine. (In the same turn, I hated all three personality constructs of Hawk from DA:II)
Given that this game is all about the role playing, I think voiceless grants the player a great deal more flexibility.
