Fun yes, it would be no fun if they did not have flying mobs you had to doge. Maybe I am complicating things more. But the thrill of going in high end zone is well not dieing as you go through. If you can just fly over everything like in wow. The only thing I would love about the mounts is the views you can get of the settings around it.

One thing about airships in this game and one in FF11 is in FF11 You got to ride them and not have cut scenes then loading screen then back to cutscene.I guess times changes and I just got to move on.
