If you give people the option to fly on one hand, they say they don't want flying because it ruins immersion, but then they use the flying because it gets them where they want to go faster, they clearly aren't that invested in the notion of not having flying.
The convenience of them having the flying trumps their personal feelings on immersion. So, what's going on here? Are these people asking Blizzard to save them from themselves?
I stand by my statement. If someone is going to push hard for something that has a negative impact on a large number of other players then they'd better stick to their guns and put their money where their mouth is. Demonstrably stop using flying mounts of your own accord or GFTO, I say.
