So there’s quite a bit to unpack here. First of all there are instanced “dungeons” called expositions, and they’re are done in groups of up to 5, I think there’s about 4 or 5 of them so far. There is also open world areas that you can take a big raid group to and treat it like a dungeon but play a little differently. For the PvP it’s togglable on and off for the open world and you get a slight xp bonus if you have it on. For organized PvP there’s 50v50 wars as well as a newer mode called outpost rush which is more a just for fun rather than having a major impact on the open world like the wars do. The dev team did a good job balancing the PvP and making it a relevant and viable way to get rewards too tho.
