So, we were playing No Mercy, 3rd map. Good game, the other team was getting all their tanks (two in this case, in the tunnel, no where to go) build up and stomping over us. Turns out, there is 4 players left, I am one of them. I die. I buy up and we are 4 people again. Two more players die and I pop some adrenalin, because I was the only main left and wanted to go for some points. We were dying in the small alleyway, everything was covered in spit, the two tanks around us blocking all entrances/exits. I either die in spit or try to get some points for this team as a main.
At this point, the last main in the map to get points for the team, no way of surviving, I think you can call this justified rushing. Not that it's possible to make it far, but apparently it's worth a ban anyways.
Here a few screenshots of the log
