Guild Atlas (Lategame koop & partyplay)

The game was a lot of fun throught the story in koop but in the lategame the game seperates the players. You dont progress your atlas when playing with friends and while it doesnt really hold your back, working together on a goal is the key for koop i think.

So why no guild atlas? It would be a specific atlas which is tied to the guild, not the players in it and follows its own rules. Maybe with events where players open up a path and then need to do as many maps as possible in a given time, because the path closes after certain time. For example to search for bosses or treasures.
Players without synergies in their party could think about letting their players run different maps while players who play together and want to do koop try to be as effective or more by doing maps together but faster. In the end it would lead to them working together to progress their atlas.

Something like that in additionn to the current atlas system would be a great addition for the lategame in my opinion.
