Since we have successfully established that El Dorado works, now we just need to gather 30 players again. To that extent, on the upcoming Sunday (02.12.2012), I invite everyone to queue for El Dorado instead of Stonehenge (and instead of Fusang, if anyone's still playing it).
Queuing for the whole day is encouraged, but, in case you don't have enough time/patience to sit in a queue for the whole day, you are welcome to queue for a couple hours starting 18:00 UTC.
To ensure you aren't bored while queuing, remember there is a whole range of PvE activities to do, namely: farming, lairs, NMs, raid. Be warned, though, if El Dorado pops while you are in a Nightmare dungeon and you accept, after the match you will end up locked out outside of the dungeon. But hey, who cares about NMs when ED's working?
Also remember that, if you are queuing as a group, if a member of your group changes zone - he is no longer queued (albeit he will still see the icon). To fix this, your should either re-queue the group or ask the zoned member to rejoin the group.
