12-20: You could stay with Rockers or move on to Peco-Pecos. Stay on with pecos to level 30 also can. A tank is possible for faster rate.
21-30: You can choose to level in Culvert until you get better or go to Smokie Forest or Byalan or stay on pecos till level 30.
31-40: Fight goblins if you have a good party. Or for a cheaper choice go to Byalan instead. It is best to solo on poporings until you can solo orc village on the orcs.
41-50: You'll feel the slowing of your progress since you don't get much exp anymore. You can try Draniliars in Coal Mines or in orc dungeon till you change job if you're really patient.
51-60: The Boring Years as I would like to call it. Continue level in orc dungeon till change job. After that proceed to level 2 for more exp.
61-70: Spnix level 2 or maybe on pryamid on the minorous if you have enough AGI and flee rate.
71-80: Try on coal mine level 3 till a certain level and proceed to turtle dungeon level 1. Your AGI must reach 99 in order to train on Turtle Island.
81+: Anywhere as long as you can handle, Turtle Island is one of the place or GH or magma.
