So, last year, you know, 2010, Blizzard announced their new Real ID plan. To which I had this to say:
None of the “good” parts of Real ID, the cross server chat, cross game chat, seeing people’s alts, and so on, required the use of real names
Blizzard did back off a little bit. And now they unveil the new BattleTag!
Short version: It’s Real ID without using your real identity.
Now if they can just allow for a character exemption or “invisible” mode so I can choose to play but not be seen by my BattleTag buddies, they’ll have covered just about everything I care about.
