One the main points I've been arguing is to take the existing and past examples of flight and expanding or improving them. This is not, and has never been, a call for a simple cut and paste of flight onto ground content.
I have to admit that I'm having trouble following your writing style, but I'll give my responses my best shot.
I am not advocating some kind of separate content that can only be done from the back of a flying mount, which excludes people who choose to go with a ground mount. While I think that would be kind of cool if Blizzard was willing to create double the content(one set for ground, one set for flight), I doubt that's entirely feasible.
What I AM advocating is allowing for different approaches to the same content. Someone on the ground has to fight their way past guards to reach a boss, while someone in the air has to dodge cannon fire to get to the same place.
Except when no one is yelling, and is instead simply pointing out the flaws of trusting someone with a proven track record of not living up to the hype in the past.
It's good to have confirmation that they're actually finalizing a plan of going with a pathfinder unlock, because now we don't have to guess at their intentions: To relegate flight to being a side show, and unusable in anything relevant.
Guess I won't be buying after all. So much for hoping they'd change their minds.
Edit: I used the wrong phrase.
