GW2 is nothing like WoW or SWtor (havnt played rift so can't say but im guessing it applies to that aswell)
As pointed out, is a exploration game. I found myself doing the Centaur Chain in Harathi Highlands 4 times a day for a week. Just cause i loved it, did it during night time so i could solo as long as possible, the first time i got passed the north/south camps was a great feeling (playing as greatsword guardian).
Now i'm 80 with my guardian and i have no idea what to do, since i don't really feel like doing SPvP and WvWvW is such a zergfest i just farm the same event over and over and having a blast.
Next thing on the list is to level a Ranger Norn.
