So it definitely looks like Blizzard intends to move forward with their plan to let hunters use a variety of pets, rather than sticking to wolves, like currently for high dps.
A lot of abilities seem similar or identical, but I'm afraid that's the price to be paid with such massive changes underway. Interestingly, a lot of the ability durations are longer than the ability cooldowns, a nice trend, which might lead to some interesting macros if that ends up as inefficient as is sounds.
All in all, looks like a huge nerf to Wasps, Moths, and Bats, unfortunately. On the flip side, Tallstriders get a nice buff, and Bears seem to be an ideal tank (Thunderstomp and Demoralizing Roar look like an amazing combination).
