the cause is too many hackers in game. You really don't know why this happened?
When they can't drive players away by stacking teams or botting.....or quitting matches and slumming with alts.
They resort to just taking down servers or other players computers.
Unfortunately thats what this community has always been. I don't even think anyone plays this game that doesn't' work in the pc industry in some way.....
normal people realize this is a fake community that is the opposite of hardcore and competitive.
Most of my family and friends (who aren't hackers, and who dont' work in the pc industry, or isn't a groupie slut houswife wannabe) stopped pc gaming years ago for the same reasons that are 10x worse nowadays.
