The game is massive and should be more than sufficient for our levelling needs, but A.Net ended up distributing the levelling process insanely poorly throughout the zones, making the whole thing feel like a chore.
The players start in lvl 1-15 zones. The problem is the zone of choice does not give you sufficient xp, the zone is simply too small for the xp you should have gained and the foes grow faster in level than the player. So the best way to play a zone, is to complete about half a starter zone, then move to a secondary starter zone, finish that one in full and then return to the first starter zone and finish it, before moving to a 15+ zone.
The game would benefit greatly by changing the starter zones from having 5 1-15 zones into having 2 1-5 zones and 3 5-15 zones. This would allow for a much more gradual progression in a zone and it would remove the need to complete a zone in full before you are even allowed to move on.
