Pet tanking in Cataclysm?

[Kalliope]

Well, to the best of my knowledge, pets have not been viable boss tanks since mid-BC when warlocks started void-tanking heroics.

Voidwalkers tanked OS+3D when it was still hard.

Marrowgar and Sindragosa have been tanked by hunter pets.

So it's later than that.

It looks like Wild Hunt only increases attack power now in the Beta.
So much for that I guess, man.... I am batting a thousand on this one! lol

Pets can block and parry, I made an argument on the WoW forums about how my druid bear can't block or parry but my pet snake can

They can? That's just.... /facepalm

The new Wild Hunt is actually pretty cool - 120% increased Basic Attack damage (but doubled Basic Attack focus cost) when the pet has over 50 focus. It means Bestial Discipline, GffT, Sic 'Em, Kindred Spirits and Owl's Focus can all increase pet DPS, since they help with Wild Hunt uptime even if the pet would otherwise be saturated with focus.
