Question: is potd the best way to level?
Answer: In a few words, the POTD is a very effective way of leveling jobs after you cleared the MSQ and so until lvl 60 where you can go to Heaven on High (that's POTD, but for lvl 61-70). Remember that joining a party should (if you don't all die because of 2 traps in a row) make things a lot faster and funnier!
