With Mists of Pandaria, account-wide achievements will indeed become available at the Battle.net account level, and many achievements will be shared among characters. A wide array of achievements will certainly be covered, including achievements that relate to everything from raiding and PvP to maxing out professions and assorted fun challenges. We really love the idea that players will at last be able to proudly display proof of the full scope of their adventures around Azeroth, regardless of which character they choose to play on any given day.
While we are still working out the details regarding how various specific achievements will interact with the new system, once we have a bit more information to share with you, we’ll certainly let you know.
Its very important that we don't need to publish our real names on the internet outside of contexts that we specifically would like clients and others might see.
People choose professional representation on all sorts of subjective and illfounded reasons. They expect a lawyer or a doctor to have certain hobbies or , better put, in making cusp decisions between two equally qualified professionals , who geta a large contract is often swayed by small intangibles.
As communication with a professional is actually a pertinent input into final sucess, picking a person to represent you who your share things with is important. The problem is that those sorts of decisions are made on tiny slivers of impressions and if, because of interenet search, one aspect of a personality becomes apparent easily, while other advocations are not, well it might give an undo weighting to one activity in their minds. (and also, others with other hobby's like hunting which attract some and repel others, can keep their intererest private except with those that they think it might create an affinity with).
There are also large safety concerns with internet stalking moving to real life stalking etc.
Long and short.... battlnet accounts need to allow an outword facing indification that is not a person's real name.
