Report Of Pet With 90% Reduced Damage Buff, Trigger Unknown (Patreon)

This post appeared on the official forums, https://us.battle.net/forums/en/wow/topic/20761807412 .

Zelshiro the hunter writes in an unusually eloquent and interesting post about how his Quillen pet has a buff which should only be appearing on the mobs at the start of the Mogu'Shan Vaults Instance, not on player-controlled minions.

Previously hunter pets maintaining characteristics they had in the wild has been a source of major exploits, this is the first reoccurrence since MOP. 

Zelshiro does not know the exact trigger and tried some experiments as explained in the post. I am trying to find the source currently. I thought I would share this with members nonetheless given the gamebreaking potential involved. It is also worth having an awareness that pet buffs may be broken generally.
