I personally would love this, especially since I have terrible luck with stuff suddenly happening RIGHT as my queue comes up. I don't want to leave but I also don't want to leave people behind me hanging so it's be nice to just let them go ahead.

But at the same time, that kind of defeats the purpose of a queue and could end up using up resources (though I could be wrong since I barely know anything about programming). A system similar to WoW where you are just paused when in a different instance seems fine to me. But a voluntary hold feature seems redundant unless there's a limit on how long you can stay paused/how many times can you stall.

So while I'd be happy if such a system was implemented, it's not something I'd push for either. I'm already used to DPS queues thanks to WoW so I can live with simply not queuing if I think I may be afk.
