I don't know if this has been suggested or not, but I would like to propose a kind of away system when you are in the clockworks.
There are times where you need a quick AFK... nature calls or someone is at your doorstep. In these ocasions, you would go AFK so that you would be kept in the group but you wouldn't delay them (so they could press the big buttons without you).
Obviously this system can be abused, maybe there would be a system to prevent it like, not allowing the person to go AFK more than once per terminal and to not allow it back in the same level as it became AFK.
Also the person would not be rewarded crowns, drops or heat.
Regards from Brazil!
Nature calls may be a serious issue. My friend's sister got a friend whose brother has shitted his pants during playing MMO. This is what you call hardcore gaming. And it's not an urban legend really...
As for the people at my doorstep, I /ignore them while gaming, unless of course it's pizza delivery ;-)
