The Dc's are an issue each run the last few is either people dcing with the authentication error, or careless people in CM not noting the changes and getting extremely careless.

CM can still be ran fast (had good groups and we cleared in in 5 mins more then normal fast runs). but the last 3 I ran into Dcers galore, or people wiping on the first boss not being aware of the new resistance addition, and unavoidable mobs.
