Skipping content is one thing - directly enabling it when you are the developer, is sheer resource suicide. You can't possible attribute it to being a bad idea without saying "Because i like flying".
There is a way that is less convinient in the game already with ground mounts. It's called Flight Paths. Very restricted and controlled evniorenments ; but it's what it does - it flies , and takes you to point B from point A. It was there for a reason.
And why do you think that creating smaller spaces is good? Because of resources and producing content at a more steady pace, which has been their goal all along - because that is what people are most clammering about, not lack of flight during 1 patch.
Feel free to point out a single thing i've been "ignoring". I've literally accounted for every single point you've made - I've countered every single point and it still stands solid. I have no bi-as ; because you don't see me going projecting my will onto stuff. I simply reason.
