a Couple things,


I have leveled almost 40 toons and there are some maps I have found to be the best.

when you are leveling 13-18 I use Balefort 4: Tower of Sorrow, there is a high concentration of NPC's and a fairly direct route to the end meaning more xp, less time.

In Alien Oasis I would complete the maps till number 5 The Great Pyramid, Not only is it a direct route with alot of NPC's but you can run to your left after you exit the walkway and end up in Anibus's pyramid and defeat him, he drops 37-40 Armors, weapons, helms

In AO2 I would try to complete maps to plasma pyramid, This is just a great leveling map.

in AO3 complete till 2: Crush the Keeper, this has a fairly direct route with good XP.

also from 28-33 I would suggest doing Ancient Swamps 5: Bye Bayou


just some preferences
