Warrior or Ranger?
I play a ranger as my main and find it very fun. The pets can get unruly but are generally more help than not and you can get yourself a bear that can fairly effectively tank for ya. Little or no problems at all while leveling up solo for the most part as well.
Farming at lvl 80 is a breeze as far as i’m concerned beyond the fact the that the mobs placement, fast respawn times and agro ranges can get you overwhelmed easily, especially if ya loose control of your pet :P
Run both as alts and both work well. Range means you have to run further to the dead mob to pick up the drop.
