I was really excited to make my Sky Golem, but now that I've experienced it for a day, gotta say... I wish I had just sold it.
It's really wonky when it flies, constantly swinging back and forth (with the occasional barrel roll). It's hard to get a bearing on exactly which direction you're heading because it's never centered on screen. This makes it really difficult to say, fly into a small doorway or land on top of something with the precision of a normal mount. Most times you'll clip into walls and object you fly alongside as it does the swing animation.
Then when you're on the ground, the thing shakes like crazy. It makes me feel like I have low blood sugar just watching it. I definitely don't see this being a mainstay mount for me.
Anyway, just my feelings on it and to say buyer/binder beware. How do you feel about it?
