Been trying to level a bloodelf Paladin on Lordaeron the last few weeks and I have noticed that i can't find enough quests to level 5 levels on just one zone alone. I played Wotlk back in 2010 and I can't recall I had to travel to 3 zones "The barrens, "Thousand Needles" and "Hillsbrad" to get from 20 to 27.

My question is, are there missing questlines, and if there is, why?
