I as well prefer lvling thrue the quests wich i somewhy consider to be faster then instances.. Maybe some do not beleave in quests or thing they will finish up too soon before you hit the lvl, but actualy it is a wrong attetude towards it (wich i as well personaly had due to my solo noob lvling experience in one area) There is so much quests in WoW it will be more then enough. Just make a HS in Shattra and move to any location you need. (there is also like 3-4 locations for each 10 lvls wich are full of quests and every pretend to lvl you from 1 to 10) i get every 10 lvls by quest clearing not more then 2 of those , maybe sometimes 3 if i know some good and easy quests from there or just i feel comfortable with this specific area)
