Unique as in the name? type? type+race?
Swarm, Stampede, Flock and what not are all the same.
Interupting Jolt was a multiround interupter before patch, now its identical to interupting gaze/backflip/kick, just mechanical
Both types of interupts got merged into 1 category, deal dmg+interupt if you go first. I do notice jolt is 4 round instead of 3 round but basedmg is 5 higher.
A Little help for people to look up abilties: http://www.wowhead.com/petabilities
quite fun indeed if you're looking for a pet with a certain ability type
And to answer your question ^^ Grunty has 3 abilties aswell; Stimpack, Gauss Rifle, U-238 rounds. For a second I believed the Pandaren Monk would have 4 but the blackout kick is indeed shared with the Qiraji Guardling so its Down to 3 abilties aswell by name
