Can't find a guild to run heroic raids? Have all your PUG encounters been epic fails? But you'd like to obtain that epic piece of loot? Introducing World of Warcraft® Micro-Buys! Now for a nominal fee you can own those items you've craved.
I see this as being popular with the casual crowd who would like to get said epics but may not have the time to get them. This would, of course, destroy the game... causing it to implode on itself. I'd imagine most of you would like to see this occur. So you should support WOW Micro-transactions (if you want to see its demise).
