Is it not easier just to have the old F1 and F2 "Yes" or "No" vote system in? It will save so much time and people getting bitchy. Or, you know, take out the maps that don't get played. It's always down to majority vote and learning which maps don't get played. I moderate CoD2, I know what maps don't get played and I remove them from rotation. I will also ask everyone if they want me to change the map. If there are more Yes votes than No then I change it. If those that voted no get pissy, tough shit really - it was a majority. So I agree with Crimson here, he did the right thing in moving the map after calling a vote.
What does annoy me though is when everyone gets into spec and starts throwing a bitch fit at those still playing.
