Alright, so long story short:
Some kind of queue you can join to get filled into a random campaign map on a set difficulty with a predetermined number of persons. Main idea is to get a more fluid and diverse gaming experience, maybe even add an aditional for this map droppable card upgrade to encourage using the random PvE matchmaking.
Main inspiration and source of this idea is the dungeon browser existing in World of Warcraft and other MMORPGs
Let me know what you think, hope you like the overall idea
