Has anyone noticed anything strange playing classic mode?
When I play, I am constantly hearing players doing ledge grabs even though there is nobody near me. When you are trying to listen for possible enemies closing in, it's a PITA to be constantly hearing these ledge grabs.
Classic mode is the only time I get it.

Me too. Only in classic mode. Sometimes I'll hear rapid machine gun fire over and over again.

I am pretty certain that this never happened pre the 1.8 patch, but then again, I didn't play that much classic..
At least I know I'm not alone
