I don't cry about it either. I'm usually the one who is fronting the enemy so my teammates can get it safely or I am killing them at their heavy. Some people are just too clueless to look around and see if teammates are running towards the heavy and I think that is where the complaints mainly come from. It benefits the team to get as many people heavy as possible to break up the other teams heavy and some people are just dumb and sit there and grab it when two teammates are running to it and are twenty feel away.
