Flying Mounts in Expansion

[Reinhart]

It looks like they're going with the invisible walls model, judging by their demonstration during the XX Live Letter, which you can see after the 1:16 mark.

Also, I rather doubt they're going to let you dismount in mid air; more likely you won't be able to dismount unless you've landed, though since we can't see the hotbars at all during the video, there's no way to say one way or the other yet.

There will be a visible wall if you fly too high

Fall damage will always stop at 1 unless in combat.
DoTs can still hurt you even if you arent in combat tho...

Why can't our chars get stuck head first into the ground like Hildy :|??
