This has been a concern for me, lately. I don't have many class/jobs pass level 20, just one level 60 for end game. My problem I have is that I don't enjoy the early-mid level content anymore, it's lonely and boring after 10-20 minutes. Dungeons are good for short play sessions when I have little time, but when I do have more time I want to do stuff in the open world that feels rewarding. I always look forward to patch days to try out the new stuff, but once I have done it a few times, I can't find anything else fun to do. I have little experienced when it comes to end game content in MMOs but I feel that it is lacking a bit of depth in this game. FATEs are boring at most levels. For me, this is because it's unsociable and too repeatitive. Might be an idea to add more random events that requires players to think about what they are doing, but I'm sure we know what would make us play more.
