The tank guide made by ryandragon on the Warrior sub forum should still be pretty relevant imo.
Best pets for a tank would be spirit salveroot seedling, spirit red Phoenix and spirit pig; with each catering to a different tanking playstyle.
Red Phoenix if your gears good enough and want to help contribute to the raid by speeding up kills, Salveroot if you’re short on vit, def or don’t mind chugging 100s of restos/caserolles every raid and Spirit Pig if you want great sustainability through energy resto/hp ticks and a decent chunk of vit.
