I am not a PvEr, but perhaps others can do this with the new Tier gear too!
I picked some pets that seem to match the theme of the new gear, or more specifically my tabard and gear, although of course I only have one piece of Ruthless thus far. I think the potential for adorable-ness is extreme
For your viewing pleasure: (and feel free to add your own, whether it be for s10 or the new Tier set, or to suggest others I can try!)
"Hello?"
