Huh. Last time I levelled a toon from scratch I hit 90 with 3 days /played, no heirlooms, just guild perk. 70 probably took less than 1 day of that. If even that's too slow for you, you could spend a few bucks on another account and RAF with heirlooms and get there in an afternoon. I don't know how much faster botting would be but certainly not enough to risk getting banned. Plus no wonder botters get fucking bored of the game so quick, you don't play it.
