Dropping out at the start of a game is one of the most common problems faced by Call of Duty: Modern Warfare 2 players. To solve this, the community is asking Activision Blizzard to bring back a "lost" feature to the game.
Previous iterations of Call of Duty let players vote on the map they want. This is notably absent in Modern Warfare 2. Because of it, players leave lobbies en masse when they end up on a map they don't like, such as Taraq and Border Crossing. Voting doesn't guarantee that players will get their preferred map, but it does give them a choice.
To be honest, we're surprised that Activision Blizzard and Infinity Ward didn't implement this feature at launch. The developers could use it to refine if not remove the maps players don't like based on which maps get the least votes.
Of course, if Infinity Ward does bring map voting back, there's the question of how it will implement the feature.
