I wanted to add that if you want a solo'able character to get you quickly, cheap, and exciting from 1-70, go Beast Mastery Hunter. Completely soloable with limited grind because your pet is your tank. Since he is taking all the damage, you dont have repair bills. You do have to spend a bit to get ammo, but its cheap compared to repairing expensive plate armor on a warrior. Ive never spent more then a gold on ammo and ive seen warriors drop serious cash repairing just to get slaughtered and have to repair again. Since your solo, you have to REALLY be careful about what your doing so you tend to have some exciting adventures running away from trains of mobs. You also have an edge on some quests because of tracking.
Sure, your not the best DPS build, cant take a hit for anything, and you tend to be the last one standing cause you can feign death ... but its plenty of fun!
