They're intentionally designed to fool as many as possible to waste large sums of money on them after all. =p
Reminds me of LoL btw, a friend that constantly complained about not being able to afford a proper computer and being stuck with a real lousy one had at that point blown enough money on LoL alone that it could've easily bought atleast two expensive alienware laptops.. Only got himself to blame for that I'd say. (And some said that a WoW subscription was expensive, hah!)
