Maybe it is time to NAME and SHAME these SCUMBAGS. Just had one in my game, tried to push others into the minefield and when that didn't work he went in himself and took 3 mines, top 30% of the top 100 and not his first offence.
Remove the "Top 100" ranking. Don't state who is where on the table, you can only check on yourself or talk to team mates/Clan members. Removes the "look at me I am a HERO", so that they have no public recognition.
