Disappointing statement from EU forums...

While you may be disappointed, this is simply a matter of the changes that would be required for these zones being considerable and the payoff being minimal at best. There is nothing within those zones that would need or require a flying mount either. We had to make a choice about allocating resources, and just couldn't reconcile the time and effort with the end result.

As for Outland, we've mentioned before that we wouldn't mind revisiting it at some point in time, but whether or not that happens is still up in the air. Again, we come back to an issue of how that would happen, why it would happen, and what sorts of resources would be needed to make it happen as a part of a larger goal of continuing to advance the game as a whole.

Time/resources would be a valid excuse, if not for the fact that blizzard is a multi billion dollar company. Just sounds like laziness to me, so what if the reward is minimal, why not follow through with your work 100%, its like leaving one side of a wall unpainted claiming you didn't have time, then say youll never bother to finish it. Also kinda like the fact that they didn't bother to do maps for the BC instances, just reeks of laziness to me, and I don't see how this much corner-cutting can be excused for a company that makes as much money as blizzard.

Though of course they have time to develop and sell sparkly horses for millions of dollars rather than polish their game and cut less corners.

Except the wall is already nicely painted. You just want wainscoting added. Which is nice and all but isn't necessary. Being able to fly isn't going to make the experience better. It's already a great experience there. We get this response a lot, but we're making smart decisions that involve the future development of the game and have put a lot of work into Cataclysm. We have more plans in store for the expansion and game as a whole as well that we are working toward.

Yes the wall is already nicely painted, but it's a different color than the rest of the room and the trim doesn't match. It really looks out of place. Analogy! :)

That's OK though, because you can see clearly that the room has a slightly different feel and theme going for it. You can't see directly into it from the other rooms, you have to sort of go around the corner first. So if it doesn't have the same color theme it still has a similar style, it still fits, just in a different way.

I have no doubt, being able to fly might make the Achievements for exploration easier, but Achievements are optional. Flying is a convenience at that point and not a necessity.
