I've noticed in Zombie V3 ever since it was released that the maps in the voting are usually a fixed pair. There are only certain pairs of maps that come up in the voting, making it not truly random.
For example: say we have 8 maps in rotation each numbered 1 to 8. When it comes time to vote on the next map, in Zombie V3 the only possible combinations will be Map 1 or Map 2, Map 3 or Map 4, Map 5 or Map 6, Map 7 or Map 8. Because the pairs are fixed, it means that there are only 4 possible combinations instead of many more and this could mean if a map is paired with another map that is extremely popular it means that the other map will never be picked because it is only ever in the voting with that same map. So what I propose is that we remove the pairing of maps in the voting and make it completely random like it was in Zombie V2.
