So it rolls to a map you don't like and you disconnect. That is fine... however. Please use etiquette choosing when to do so.
Recently there has been an uptick in players leaving in the middle of the map. Often from one side. If your playing with your partner and you both leave from a team down by one player. Now that team is down by 3 and someone is due to get flipped.
When they do, they will often leave. Some players prefer to start and end on one team.
It's not whether you leave, it's knowing how to do it so it isn't hurtful to the server.
The incidents I'm speaking of are happening when things are going well. It's not because one team is getting pounded. It's simply players choosing to play only a portion of a map.
Please be aware of when you leave the server so as not to cause another player to be switched.
Admins can help to some degree in balancing early stages of the game. They can disable auto balance allowing some player preference if asked. They will often take action to avoid a player being moved. Including changing teams themselves to fill the void.
Please assist them and be conscious of the other players in the game.
