Very late here, so here are some random disorganized thoughts, not exclusive to DT:

-Combat, outside the context of group play, feels really bad and I have no idea how to fix that.
-Combat Scenarios are usually too long, enemies are too spongy, they feel unrewarding and like a waste of time. They are also still single player only and its baffling for a mmo, playing alongside friends is frustrating.
-New zones might as well be a big grey square. Which is funny considering how long they spend showing the visual design of new zones. There's no exploring, there's no quest sending me to a interesting place, no secret locations/rewards, even the gathering points are 100% fixed.
-Independent from the quality of the story, the framework for it just feels all wrong. I'm not the adventurer exploring places, talking to people, discovering things or solving problems. I'm the muscle for the anime Scooby Gang being hand held through places I'd rather not be.
