I am not talking about the usual dungeon queue system. This is about the queue to fill in a missing group member.
There is zero way it's not broken, it almost never fills a missing dps until the very end of the dungeon which makes no sense considering the game has an overfill of dps players.
I also have never even joined a dungeon that's already in progress besides maybe once or twice as any roles. With how many people that end up leaving any random dungeon that's not FG1, you'd think having this fixed would greatly improve the queues for dps players. Almost every dps is clogged up in the queue waiting for a brand new dungeon meanwhile a group is struggling without their other dps.
And if this is somehow intentional then I don't see the point, sure some people might hate joining a group mid dungeon but it's better than sitting for half an hour waiting.
