Im not 80 (yet

) but LVL62 and pretty good farmed and all i can say that it's a good build and fun to play.

The best is to test a friend's char first though. And it's all about you, like fast lvlings = pure int etc etc. I was fully farmed until lvl56 and it rocked! I killed my own lvl and 1-2 lvl's over pretty easy.
