The only people really over the moon about the flying ban are World PvP advocates and idiots that think tedious travel time and corpse running is gameplay worth preserving. By their 3rd alt even these die hards will be bitching too. The rest only can muster a "it's not a big deal" bc even they can't deny it's an inconvenience. It's just not "game-breaking"
And of course there's the fact that Blizz does intend to permanently ban flying in all current content from here on out. The big headline was no flying in Draenor til 6.1, the fine print is that they are only allowing flying in 6.1 bc they intend to release a new zone which also bans flying.
So you can fly, but only in zones you no longer really spend any time in. You'll also have to complete some BS quest bc forcing you to drop another 1000g on an ability you've had for 6 years wasn't enough of an imposition.
And all the while they will keep trying to sell you $25 Flying Mounts.
