Well i would like to propose this.
Imagine we play a map, when that map ends, we vote for the next map.Ok so far?
When that map ends too, then in the vote options there has NOT to be the same map available, so we get away from the old headpain where same maps were playing all the time along, and making the servers too boring...
I think an IQ where the server controls how many times are maps played and which maps are not played at all would be great.
Okey, that was just an idea...Maybe it's far away from the real possible features we may see in cod4
