Realistically, this all depends on what type of gamer you are. Did you play GW1? Did you play WoW? Which did you enjoy more? The endless carrot, or the pvp game with decent pve on the side? Pve is even much better in GW2. I play this game more than I should currently and am nowhere near burning myself out to be perfectly honest GW2 is eccentric and that is why I love it and will continue to play unhealthy amounts for quite some time.
