So, up until 4.0.6, on my druid when Archaeologizing (shut up, it's a word), I'd have to mount up, since for whatever reason, I wouldn't be able to cast survey from Flight Form.
Apparently, now you can, it just drops you from flight form, which isn't so hard to believe. This could help to save a little time while Archaeologizing Druids. Yeah, sure, only 1.5 sec per survey, but that can add up.
