Zoris, you sound like you should take a break from playing. The only explanation for feeling like you both “really like the game” and feeling uninterested and bored is that you like the idea of the game. You’re hoping that the game will get more interesting as you get higher level, a common theme in the mmo’s you’ve played. GW2 doesn’t do that. The game doesn’t change much, so if you aren’t interested now then you won’t be interested in 10, 20, or 40 levels either.
Walk away from the game, think about the idea of the game, and come back later when you get inspired. Hopefully then you will enjoy your current progress.
Don’t play solely for the future.
