Level too low for map.
I have noticed this as well in the human starting areas. What you can do is go to one of the other starter areas, you can reach them by going to Lions Arch and then going through one of the portals to one of the other races home city. Hope this is of some help.
Yea, the human starting zone just doesn’t seem to have as many dynamic events as the other starting zones. I don’t know if that’s because they are more spread out, or if they’re just bugged right now, or something else, but I’ve noticed that both times I played through humans and have never had the problem on any other race.
I use gw2cartographers.com to see which other zones are the right level. As Pyrrhic said, Lion’s Arch makes jumping around the map a lot easier. And you can always get to Lion’s Arch for free by using the PvP tab of your hero pane to jump to Mists and take the portal.
Other than questions, map the region, gather everything you can, learn a craft and use discoveries. Even ressing dead NPC’s gives you xp :P literally everything you do can help you level so use your surroundings. If you are still lacking levels then go and play through other areas You get to learn more about the game while levelling and mapping. Crafting is for the awesome though once you learn how to do it right, took me a while to figure out what I was supposed to do haha :P
