Favorite companion non-combat pet?
Again, another one that is no contest. My favorite non-combat pet is definitely the Pandaren Monk. I actually only got this pet a few days ago (thank you, Spellpower), but I already knew it would be my favorite just from seeing others with them. The karate moves and the little Hee-yah's make him really unique.
If I got to pick the next playable race and class I would definitely pick the Pandaren for race and the Monk for class. I know that it will never happen though, since China will not allow sales of the game if it includes pandas.
If we exclude the pets that can be bought at the Blizzard Store, then next on my list would be the Sprite Darter Hatchling, which apparently is no longer obtainable since the quest is gone.
