bennyboy: Necromancers start off strong but grow terribly slowly, so that's about right. You can start in the Plains at Level 1, instead of waiting to 15 like other classes; but then you'll be stuck in the cave or desert for like 20+ levels.
Kevin: if you go to the plains at low level, you get killed and returned to the city. you need to build levels in the forest before going to the plains.
My philosophy is this: it's an idle game. Start character, put it in the forest... Go to work/school, go to sleep... get up the next day, and put it in the plains. Go to work/school, go to sleep... get up the next day and put it in the cave. etc.
