The sky IS falling! They are removing Ancestral Swiftness from the enhancement tree.... Back when mounting was a 3 second cast time, ghost wolf at 2 seconds was a nice way to get around quickly for short distances, but having it instant was very nice to have in PvP. Hopefully they are either making ghost wolf have no cast time as a baseline skill, or moving the talent elsewhere.... But it is still beta and will probably keep changing... I should really stop reading cata news...
