So how much money would it take to become TEH UBER? They land on a figure of $23,015 (not counting the $100,000 they say you'd have to pay to get everyone on your server to treat you with the respect you'd actually get if you were that uber). Which seems high, of course, not to mention that you're missing out all the good stuff-- the leveling and raiding you'd be doing while playing your way to the top. Would you pay $23,015 to have the absolute best character on your server? I sure wouldn't.
But I'd take it. If you want to give me $23k and six months, I'll be happy to quit my job (later, WoW Insider!) and get you exactly the character they describe. But then the question is, as NotAddicted says, what would you do if you really were the uber-est character around? Rock the battlefields? Gank newbies? Dance naked in front of Orgrimmar?
