Want to level a character quick and have it on level 80 in no time? Check out my free WoW Character Levelling guide! It is good for Horde and Alliance alike and guaranteed to work!
Step 1: Make an alt.
Step 2: Level it to level 15 using the starting zone quests and the first followup zone.
Step 3: Queue for random dungeons.
Step 4-120: Run random dungeons until level 80.
While waiting for your dungeon queue, you can quest or grind boars or level a profession.
Really not much to it, eh?
