I can't say for everyone that they have run into a team killer before, and as we all know, that is against the rules! It could just be me but I'm almost certain atleast a small group follow this complaint. I know some people may use the TNT kit for its intended purposes, but I haven't seen that happen before. What people are doing is placing TNT near teammates, and blowing them up, which is an obvious act of team killing. I'm not saying remove the kit completely, but it should be nerfed or made team-kill proof.
