78-80 Northrend Crystalsong Forest (Horde/Alliance) 1.0.0

This is a nice spot I used to level two warriors from 75-80. I had heirloom gear for both though so if your toon isn't very strong you should wait until you're 78. It has good exp for leveling and there are both Horde and Alliance FPs & vendors very close. The location is pretty secluded though so I never saw any other players there. There are a couple things you can skin and tree mobs you can harvest for herbs.
