The always interesting Mania's Arcania has more great news for Hunters from the PTR blog. Apparently in 2.2 (and right now on the PTR), Raptor family pets will be able to learn the Dash ability. Previously, I believe, Dash was primarily available from the cats in STV (Bhag'thera, the elite panther down there, gave Dash rank 2). But now Raptors are getting in on the speedy fun, too.
Now, Raptors can already learn to both Bite and Claw (they can Growl and Cower, too, but those are the standard pet abilities that every pet has), so you might think a third ability would make them a little OP. But it turns out Raptors have been getting the short end of the stick for a while-- Cats can do all those things and Prowl, and Boars even get an extra Charge ability. Heck, even Tallstriders can Dash, so a Raptor doing it is no problem.
Bears, it seems, are stuck with the short of the stick, as they only have the Bite and Claw. But Bears get extra HP and Armor, plus a lumbering bear isn't exactly sprightly, so Bear-owning Hunters don't have much to complain about. If you're a Raptor kind of Hunter, make sure to stop by the pet trainer after 2.2, because your pet, clever girl, has picked up a new skill.
