I was super excited about being able to fly when I purchased Stormblood, but I quickly realized that due to the shitty landscape/terrain, flying is more of a necessity than a nifty little perk of the expansion. As soon as I entered a new area, finding the aether currents and completing aether current quests was the first thing I did.
Also, to piggyback off of your post, I think it's dumb that the holiday bear can fly.
