Interesting about the mounting through things that aren't solid, and not needing to DC anymore. Its a good thing something works well out of everything that has been fixed!
And like ParceQueFraiSe said, we need a better solution, because not all underground explorations have the luxury of models to fly around, like in Stormwind. It is going to be a real pain in the ass until we can find a way to fly under the ground without having to lag out or be near WMO's.
