Ok we know how you get triple xp with the RAF thing, but some people might already have a lvl 30 - 58 alt they want to level without having to level another alt to 30 first. Simply create a level 1 toon, let it die so that it becomes a ghost, and put it on follow on your lvl 30 alt! Now you can quest like normal on your level 30 and still receive triple XP bonus from everything! The good thing about this is that the level 1 wont pull agro from the lvl 30 mobs around you when you are questing on it.
For this to work you need the 2 accounts, and to have 2 WoW's running so that you can control both toons, eg. dual boxing.
