Yep it’s ridiculous - you already have no idea what the person has up their sleeve based on class why are pets magically different?
I still have my Auberdine Thistle Bear called Mauler that I tamed back in 2004 on release week as it had a knockdown making taming hard and it became a personal challenge to tame one.
He has been with me every raid, every dungeon, every step of every expansion.
It sucks having him nerfed for being the “wrong” spec now they’ve taken that away.
