I don't understand, you want a ban request for someone who dies quickly to your sword? He is hardly leeching since he got a kill in the second screen shot.
It's against the rules to rejoin? News to me.
If you are in a position to rejoin right away, you most likely died without killing ANYONE and were instantly shot from across the map or cav'd from behind. You can't make any major contribution to the team and make the respawn time window. I don't see how this gives any big advantage.
Why make it against the rules when you could just fix it? I don't understand, man!
How do yo propose fixing it?
