All we had played official so you know how to exp and farm.
Moreover, this is a long story how you become from 1 to full LvL and hero.
You need a lot of work for that. But I would like to give an example.
LvL 1 : Elven Village until LvL 12.
LvL 12: Ruins of Despair until LvL 20. You got the first class quest you do that.
LvL 20: Execution Grounds until 30-35
LvL 35: Cruma Tower or in your Level Zone didn't remember this level stage until 40-41
LvL 41: The Cemetary until 47-50
LvL 50: Forbidden Gateway until 60.
LvL 60: Tower of Insolence called "Toi".
Anyway when you reach the full you just make a buffer a spoiler as you said and friend of yours a healer. That would be great.
Also, mages for a nice farm. Oh and do not craft just buy them ready from the Shop Towns like Giran, Aden, Dion and etc.
