Issue with voice overs is most games have their npcs say 1 of 5 lines with 1 of voices, Rift is a good example here "death to the dragons" by 80% of the npcs with the same voice for every situation..... If they are going to do voice overs well they will have to spend a small fortune on it honestly, in multiple languages. It would be nice if they had it but they would have to make it good... something I have not seen in a mmo yet and there is a 1000 other things SE needs to finish before this.

As for auto-attack speed they already said it is not finished and they did this to allow things like multiple attacking weapons and haste gear.
