While the vast majority of battlepets are drawing from the same pool of moves (just renamed), I will say these have some stronger movesets than in recent memory
Only putting pets in the first raid tier is a bit odd though, but TBC and Wrath had just 3 instances of pets too (Cata had everything). You'd think Ravenous Prideling would have dropped from Sha of Pride in SoO and it might have originally been created for that purpose. After all, the Grand Empress fight involved possession from the Sha of Fear instead
The flavor text even references that it's a spawn of the Sha of Pride (most dangerous Sha)
