I have two tenacity pets, and three ferocity, so it's near impossible for me to play another other than bm (at least that's with my thinking)
The current list is: King Krush, Arcturis, Gezzarak the Huntress, Skoll, and the Hydralisk!
King Krush and Gezzarak I refuse to abandon, I love how Arcturis looks, Hydralisk is a hydra, and Skoll holds sentimental value.
That said, I rarely use Gezzarak, Skoll, and the Hydralisk... It's hard to find place in heroics for the tenacity pets. I'm hoping at least Warpstalkers can be chosen to be ferocity someday

So who should I abandon, or return to the wild? Should I just keep them all?
