Yeah, I've heard that sometimes it does, but on the other hand, people have done otherwise. However, when you think this is true, then you must consider that designers may have done it in the past. That being said, we all agree that it might happen. Now, knowing WoW is an MMO, you can't really take this into account. FFS, can't you just, first wait for the expansion to actually come out in 13 days, enjoy it, and may be, i mean may be, talk about the futur in several month...
