First Off, ALL these leveling services use bots. only thing i would buy from them is gold. i go to Wowyour.com , i have Wigsplitta do my powerleveling. also you get banned when they use bots and stay online 24-7. Also blizzard tracks the constant different IP's being used in that 24-7 playing time.

So the best bet is to have someone you know do the leveling like Wigsplitta!
