Disable all cs in pf unsynched groups

[NephthysVasudan]

It's almost as if what you're complaining about in entirely avoidable.

Unlike with DF runs, you have the option to ask your PF members if they are planning to watch CSs prior to entering the instance. If so, simply don't join. Why spend effort implementing something that is easily solved with basic communication?

Basic Communication requires common sense and intelligence to read before you click..let alone think before you leap....not that i'm disagreeing with you of course.
