MW2 automatically selects hosts for matches. When it selects me, two outcomes occur:
It turns into a lag fest. You may think I benefit as host, but no. I’m lagging too.
People time out and others cannot connect. Games do not have enough players.
Despite these problems, MW2 continues to choose me as host.
Perhaps there should be a “you suck at hosting” list or even an opt out of hosting option. But Big Brother IW is rolling in $$$ so I doubt anything will change.
