So I havent had to level in the old world in a long time (cause i dont make that many characters) but my brother started playing again so Im making a team over on his server. i moved an 80 there so I could boost. I am hoping somebody can tell me how they go about boosting non-RAF. Im going

1-10 starter zone solo
10-20 Shadow Fang Keep
20-35 SM cathedral


After that i dont really remember where to go optimally. I would guess ZF but im hoping not cause I hate ZF.

If anybody would share what they do for 35-58 so I can get to outlands (at which point things become much easier) that would be awesome, thanks.

P..S. Searched for boosting guides but didnt find much laid out, sorry if this is a repeat.
