Give them a hand, and expect to lose an arm.
I could start this post with I told you so, but where would be the point. My stance on Blizzard and their number of weird, and in my opinion wrong calls of late is well known, so I don't think it bears repeating. The only good thing that we got out of Warlords of Draenor were the new models. For the rest I cannot judge because I did not buy the expansion. One of the primary reasons being not knowing if we would be able to fly or not.
To some, this might appear as trivial, to me it is essential. When Blizzard says they don't want us to skip content, I am thinking of how annoying it is to kill a bunch of mobs that you don't need. They are just annoyance, I don't even perceive them as a challenge or obstacle. They are just there to waste my precious time. With flying I can circumvent them and be on my way, doing something that actually excites me. Without flying I am back to square one. Imagine saving Kull day after day without flying. A bloody nightmare. Flying made that daily quest bearable and maybe even exciting for a bit. Even if Kull really was incorrigible jackass.
