As I was there for the whole event involving Bingus I will explain it from a staff point of view, I wasn't the one who warned old mate but like I said just from my POV. Once the EC was tied to the wall and the EM gave the order to kill him Bingus then pulled out his Smart Launcher and then shot it at the ground near the EC killing himself and 16 other players not 10, Some of the people killed were staff members which I can tell you now they were not laughing it off, after the staff member found out how many people Bingus killed he instantly got taken into a sit and punished for his thoughtless actions. I can also tell you know that only JT's were the ones "Laughing it off" as majority of the players killed were complaining to staff about the event. I hope you can understand our point of view as the Staff Member that banned him pretty much let him off the hook, If it was me he would of got a much harsher punishment.
Also the fact of you saying people were starting to disconnect is 100% false the EC was still getting killed in the firing line at the time Bingus shot the rocket.
