How easy/intuitive is it to find people to party up with? I really like Guild Wars 2 because it was easy to party up with or work together in events and whatnot.
It's interesting because you have the GW2 type open world stuff which people constantly form parties for, and then you have the WoW type dungeons which rely on the holy trinity of tank, healer and DPS and are really pretty rigid and old-fashioned.
