Totally agree in voice acting for the character, i know that is a huge amount of resources even only two voices (one male and one female) but for me is very inmersion breaking have a mute character in a world that everother can talk.

Mute character can always be left as an option for people who prefer this or for those who can't accept an elf talking with the same voice as a dwarf.

Lips sincronization and facial espression problens are truly here but i'm confident that it's more an EA thing, in fact i'm surprise the EA included cinematic camera at all, i know that they are going to put it in the game but think it will be left for the final game
