Okay so, firstly I will begin with how it says it will strike after “multiple games” yet you only have to leave one to get banned. Yes, I get it’s annoying when someone rage quits but I didn’t pay 50 quid to get banned for 20 minutes.
The worst experience I’ve had with this was I was playing Breakout with my friends. We were getting thrashed and they got fed up and slowly left one by one, it was now just me on about Round 4, me winning one (when I previously had my friends with me) and the other team with three and the next Round started and I thought “No way I’m winning, this is humiliating” so then of course “The banhammer strikes” and yeah okay I left dumb that I got banned after leaving just one game but I’ll tolerate it, then checking the duration of the ban and… six hours. Six hours. It was genuinely the dumbest thing which has ever happened to me on Halo 5 excluding falling through the map.
