David Vonderhaar has confirmed on Twitter that the long awaited change to map voting will come with the next Black Ops 3 update. For those unaware, the issue is that there is no limit to the amount of times you can vote on the previously played map which has resulted in the same map (usually Combine) always getting played.
@thejamessutton Next game update … and also you need to throw in premium seats.
