I'm pretty hyped, I love the communication from them! I've still got so much to do from icebrood and EoD, time to dive back in I guess!
My only worry about the sky scale is how they talk about buffing its movement, it sounds fun but it's also already the most powerful mount. Hard to imagine a use for our bunny or raptor if we're zipping over queensdale on our dragon. Guess it matters less if everyone's got it, no more leaving new folks out.
As far as I can tell, they aren't buffing the speed, but it gains a lot of new utility. Being able to mount in combat sounds quite broken, and will apparently not be possible with the other mounts.
