Ehy Guardian. Unfortunately Bungie has implemented a Leave Penalty in Quickmatch because since SBMM has returned the number of leavers in Quickplay has increased by a lot. Now, leavers have always been a problem, but it seems that between stacks, SBMM and a certain hate towards some Maps, leavers have drasticaly increased and Bungie took this drastic decision. Personally speaking I disagree with it =/ I don't think it was properly implemented and doesn't take in consideration factors such as disconnections or error codes, but I'm afraid there's no much to do for now. We have to wait and see Bungie's feedback about it if they will decide to keep it or remove it.
