On some maps you can plant mines on your own team’s spawn area, and therefore could just kill your own team without much problem. Removing the ability to complain would be a bad idea.
I’m getting annoyed by these kinds of requests, actually.
The strength of such a game, and any team based game, really, is freedom of choice. You have a variety of skills, classes, and weaponry at your disposal, but you can’t do everything by yourself all at once. Each player has the same freedom, and the key to victory is making the decision to work together, and applying your skills. Removing options to complain, call votes, or run off and do stupid things would result in a cataclysmic loss of the core dynamic elements of this game.
And so we see the nature of our existence mirrored in a game - alway willing to trade another’s freedom, but never willing to give up our own. You should be careful with your mine placement, pick it as carefully as you pick your shots. You must remember that other players have the same freedoms and responsibilities, and there is always the chance they might not see your mine, or they might see it and try to see if they can leap over it. They might complain, they might not.
