What about the tank mounts? These give you a reason to do dungeons as a tank. A lot of people farm an easy trial instead but you can do it through roulettes instead to give yourself a reason to do them.
As you acknowledged there is plenty to do in the game. You could collect all the mounts, all the minions, all the Triple Triad cards, and those goals alone would keep you busy for a very long time, because some of the things you collect involve months-long grinds.
