Came across a new one yesterday playing market garden. Team Annoyancers. 2 people were shooting teammates until their health was low, in effect killing them, but letting the enemy finish them off. Of course with that we can't file complaints, and voting was not enabled on the server (why disable voting?). One guy would go and destroy the mg40s, and even blocked the way to the dyno when it was planted by the enemy to prevent us from defusing it.
TK should be based on who does the most damage in a kill (within the last 10 secs, not who gives the final blow. It would be better for points (ie point whores would be happy) and it would prevent this crap from happening.
