In the alpha you would level cap after 2 zone.
They nerfed it. I'm level 109 currenty and I just began Highmountain (like I did 4 quests).
Also "look in the world" is kinda funny since those side quests are just next to the main quest areas.
=> they just need to boost the exp a little/nerf the required exp.
The ideal would be : 3 zones to level cap.
