In my opinion, I believe it's that players just like the power flying mount provides and anything affecting that generates negative feedback. 3D combat in vashjr and 4wind was really nice to me personally speaking. I also never dodged oculus as that was 1 of the fastest heroics for people who knows what to do.
No need to insult Blizzard's skill and creativity. As a gaming company, they are better than many other companies out there and have created some long lasting successful IPs.
