That's a question — and also a regret — I have about this game.

I started playing at the beginning of its release with my friends, and one of the reasons we stopped was the lack of real PvE content — it was only about mob grinding and a few bosses.
I remember when some PvE players asked: "Why are there no dungeons or PvE queues?" The staff replied that they wanted to keep the game open-world and didn’t want instanced PvE content.
But now, the game has multiple PvP queues — yet still no PvE queue. I think that’s a real shortcoming.
I'm pretty sure that if the developers introduced dungeons, a whole lot of players would come back to the game.

Just to be clear, this post isn't meant to stir up controversy or spark any conflict with PvP players. Adding PvE content wouldn’t interfere with PvP, as most PvE and PvP players are, in practice, two distinct communities. There’s room for both to thrive without taking anything away from the other.

Techncially, the game has dungeons, they are just BDO-style. And you dont really have a queue for it (other than for the season version), but you have to find your own teams, which you can also do through the party finder. But if you want instanced group pve content then theres both atoraxxion and party black shrines

Technically, there is an Attaraxion Party Matching system. However, people don't use it very much unfortunetely.

There are dungeons, and dungeon-queues already. There is also the party finder. So everything you want exists, you just didn't know about it.
