I like flying for flyings sake. People can talk about grand vistas and size of zones, or it invalidates content. I don't care. Flying is fun. Shear sensation of flying has no equal, no mount speed, no jumping game. Nothing. I often just fly around random zones for the sake of flying. I did that in WoW and I do it here. Flying is awesome.

Do you know why people dream of Flying but not riding? Because Flying is awesome.

Do you know how many super heroes fly? Do you know how many of them swing from above? Now compare the number who.. walk places. Flying is awesome.

the Wright Brothers were Bicycle builders and the inventors of aircraft. You know why no matter how good a bicycle they made we don't care about it today? Because Flying is awesome.

The Kakapo is a oversized Flightless Parrot that has less than 100 of them left alive on the planet. You know why? Because they can't fly.

To Summarize, Flying is awesome.
