My thinking is...
That's
Not
Vanilla
As I've said before, frankly, I don't care what they do or don't do. But if people have been bitching for so long about how supremely better Vanilla was than current WoW, they should get exactly what Vanilla WoW was. With no shine, no polish, no extra fluff or anything like that. If Vanilla was so great, then ver batim vanilla should be presented, and we'll see how "great" it is versus how greatly it was remembered.
