When ALL my kids were little tots, if they touched something hot and got burned, they didn't go near anything hot anymore...when they got older and bolder, they would do something stupid and get hurt or even burned, but after that they didn't do it anymore....
I know most of you play AS/MP, but it is messed up, how many times do you have to get burned to figure it out....
"Just sayin", don't play it and they will find a fix post haste....
