People not rolling in duties - can we do something about it?

[Andres_Lonegrief]

And how do you tell if someone is afk because he needs to or if he's afk because he wants to?

there have been times where the guy who didn't roll was running around, so it was quite clear. Other were spamming emotes or chatting. Also, if it was something from real life it wouldn't happen so often.
