I'm sure this has happened to all of us: One of the party members goes "brb" and goes AFK for 5 minutes. Leaving the rest of you to stand at the Party Button or Elevator. The worst part is, he's the party leader so you can't kick him. Here is my suggestion: Make a Hibernate Option.

This could either be an automatic thing when they don't move for more than one minute or a button activated. When activated, they go into a mode where they're 'dead' and have the "A Party Member has revived you" text. This will allow you to step on Party Buttons and Elevators without having to wait. When they do actually return to the game and come back to life they have the same health as they did before they Hibernated. Normal death rules will still apply, meaning that if the rest of the party steps on a party button then they'll be teleported there. However, if the rest of the party gets onto an elevator and goes down, the AFKer will keep his heat. Players can still be kicked or joined while they are Hibernating.

For discussions on which Hibernation system to use, refer to them as 1, 2 and 3.

1) Automatic Hibernation: The player automatically Hibernates when the player is AFK for a certain time.

2) Self Hibernation: The player can set himself to Hibernate manually with a button press, or an option on the GUI.

3) Party Leader Hibernation: Hibernation can be done by the Party Leader, to any member of the party.

The ability to Hibernate could have a cooldown or not to prevent abusing. Discuss.
