No offense, but I think you're over-interpreting what I'm trying to say. I'm simply surprised that they want to take away flight until lvl 90, and surprised that people at the convention were overwhelmingly in support of it (based on what you saw there). I think if they do there will be a lot of people who will be irked about it, partly because flying is fun and a lot of people have paid gold for it, farmed certain mounts, etc.It certainly reads like you're not someone in love with questing, which Cataclysm's flight elevator-enabled style of questing really made a lot less meaningful. Many players, though, really missed the first time they rode on horseback (or wolfback, or whatever) into Dragonblight or Nagrand, etc., which is a lot less impressive when you can just fly on through.
I understand the reasons why Blizzard wants to do so, but it wouldn't put me off the game at all. Questing is the thing I enjoy most about WoW, followed by exploration second. It's true that I'm not terribly fond of getting randomly attacked by mobs when I'm simply trying to move through one area to get to another, and flight is good for that. But so is a super-fast ground mount.
