First of all, I would like to state that I love that the Adamantoise mount can fly now. I think it's a great addition to a decently expensive Gold Saucer reward. It feels right to me that the mount I worked hard to get is still viable in the flying areas, so thank you, dev team.
That being said, GOOD LORD it needs to not spin like a top! I absolutely love the "jet pack" feel of the flight, but "brb barfing!" If we could just have everything about the flight except the spinning, it would be perfect!
