I remember when World of Warcraft first came out, and it was actually fun to do some quests, and discover new territories, and kill a couple hundred bears or murlocs or what have you, and get all excited when you got a new level and got to pick new skills or talents, or finally got to wear a wizard hat or get a mount. But come on, how many times can you really do that before it gets old. No one is fooled, Blizzard. There are like 5 quests that get repeated over and over, just with different beasts to kill, items to gather, etc. I just made my Death Knight, and I played for only a couple hours, doing some quests, testing my spells, before already getting bored with the leveling process. And this is with a brand new expansion and an obvious effort by Blizzard to make the quests interesting, like the Eye of Acherus and the stealing the horse ones. Yeah those quests were kind of cool. Enough to make me want to quest for hours and days until I get from level 55 to 80? Nope.
Also note that power leveling is sometimes used to refer to paying someone else to level your character to cap as fast as possible (i.e. they power level for you); a distinction used by Blizzard is to refer to the paid leveling as "power leveling service." This behavior is against Blizzard's Terms of Service. Power leveling yourself, which this article covers, is perfectly acceptable.
Drustvar is far and away the hardest Alliance zone, which is exactly why you want to do it first. If you have legendary items, they’ll still be usable, and if you don’t, this zone will still be easier early on than it will be later. Drustvar is also extremely fast and will let you jump out ahead of your competition in other zones, which means fewer players around to take your quest objectives.
