The players Dewayne Clubb comments on the "Patch 5.4 PTR Datamine: 100% XP Buff via Microtransaction " says:
People quit your whining.  When content becomes stale or you don't have anyone to play with or you're not a hardcore raider this is perfect for someone like me who likes to play solo but has the option of playing wow with others at any given time to get much gold and coin on http://www.pkpkg.com.

I have 11 characters only and only because I'm not a hardcore raider and because I needed other professions to help my main character out because the auction house prices on my server were beyond out of control.

So this is the one transaction I will definitely be paying for from the Blizzard store if it comes to see the light of day if it turns out to be true.  It will make leveling my alts so much easier as leveling was quicker and the content in burning crusade and wrath of the lich king storylines were much more interesting and enjoyable than in Mists of pandaria and cataclysm.   I quit for the entire expansion of cataclysm because of the hellish grind it turned into and just about quit pandaria because of what its turned into because I don't like grinds.  Wrath and burning crusade were nothing like this.  They and by they I mean the developers can't seem to find a middle ground.  They either cater to the casual players or the hardcore players.
