There's a new post, apparently the Duty Finder will be in from the start of this test. They still haven't communicated an end date for this test however, so it's possible it'll last longer than usual still. They also released a video showing the duty finder.
It's basically what you'd expect, you queue as a certain class, when it pops you have to change back to the class you queued as(no carpenter tank), it's cross server and you can choose your languages so you can group with japanese or euro players which is nice if you play off hours, it teleports you inside the dungeon and teleports you back out when you exit and there's an option to join an instance that's already underway so if you don't care about the loot and just want quest completion for example you can do that and it'll join into an existing group that had a player that dropped. It also level syncs you down if you wanna do lower lvl content for whatever reason. Seems fairly complete and while it kinda kills community/sense of world etc etc, it's still nice to have I guess.
