Thoughts -
Cunning:
Mobility makes more sense now and the Owl's Focus buff is nice. Roar of Recovery had a pretty sizable mana nerf, but it's now much easier to use with the Range increase. Sadly the tree remains a little lackluster to me with its Happiness ability, Carrion Feeder, being pretty much terrible compared to Loyalty and Guard Dog in the other two trees.
Ferocity:
Call of the Wild's focus cost is still a terrible 100. It got a very nice buff and is much more usable with the range increase, but the focus cost is still a big problem. I think 60 would be a little more in line with the other stuff. Loyalty got a little nerf, but it's still fantastic and a must. Rabid's CD makes more sense now. Lick Your Wounds is now better, maybe actually worth using (if you're BM with spare points). Definitely still loving the Ferocity tree all around.
Tenacity:
The Tenacity tree has some good improvements and now I may considering leveling with it over a Ferocity pet. The new Guard Dog talent is pretty much win. Roar of Sacrifice: 3 second cool down? Is that a bug? That CD must be a bug. Anyways, it's a much better ability than the one it replaced.
There's some nice changes over all and it's good that many of the abilities make a bit more sense now. There's still definitely work to be done though and some fleshing out to do.
