[ANSWERED]Explain me the que

can you explain to me if there are 10 000 people online why i have to wait 50 + min to join Heroick dungeon ??
can you explain to me how 800 people queue is 9 hours and after 23:30 in my country it goes for 10 minutes but all day coudnt connect ???
I'm really curious

The queue obviously depends on when other players logout to allow someone else to get in, so the time frame you see is a bare estimation.
