Did you read my question?
Really? Did you read my question? I'm curious why nothing was done about this before now. That's all.
If content is compromised to such a steep degree, why not say before Wrath "Look, we gave it a go and we don't like wow po where this is leading our game. We're pulling flight now before this gets out of hand."
Instead...they designed entire zones to require it in Wrath, sold a lot of copies of the Cataclysm expansion on the back of "You can fly in Azeroth now!" and began marketing flying mounts in their Pet Store, to say nothing of countless in-game rewards of flying mounts that will look ridiculous as ground mounts in WoD.
