The queue system is in a desperate need of a rework, with the low amount of players it takes way too much time find a party for anything.
Proposed solution: Allow players to continue doing their thing, be it questing, farming etc while they’re queuing for a Dungeon/Mission.
I know this would require some work but if you want to save this game from dying due to people spending half a day in queue then this needs to happen.
This, more than anything discourages me from playing the game because, well, I can’t play the game when I’m stuck in a queue for several hours a day.
