Flawless Stone - Pick a pet to use

[Gude]

Choose 3 pets to use Flawless Stone, just for fun and to elabore a list of nice pets do upgrade

[Bistromath]

Black Tabby Cat - This was my first pet i ever got off ofa Dalaran Spellscribe along long time ago, go it on the 3rd mob i killed

Larva - I hate looking for this one in rare quility

Curious Wolvar Pup - He just looks BA

[Hellomynameis]

The pets I have used non-family specific stones to upgrade with, are as follows:
-Tranquil Mechanical Yeti (mech)
-Peddlefeet (humanoid)
-Scourged Whelpling (undead)

Yes, I have actually gotten 3 of them, go figure.

Ghostly Skull (breed 7), Mechanical Pandaren Dragonling, Yellow Moth (breed 4).

On Warla's site, http://schaffhauser.me/Warcraft#PetBreeds (are they still censoring this link?), you can see the possible rarities that pets come in, based on armory profiles. So you can see which of the pre-MoP uncommon pets that people have chosen to upgrade--I was surprised at how many different pets have been upgraded by at least somebody out there (ie somebody upgraded an Orange Tabby Cat, a Black Kingsnake, the vendor moths, etc etc).

So far, I have only upgraded Willy so far. He's my avatar, a Magic-based pet, and he's just a fun pet. Granted, he's only 4 right now, but I have high hopes for him.

On the horizon, if I can ever get another one, would likely be:
Legs (Another great Children's Week magic pet. Has strong attacks.)
Baby Ape (Between this and Giraffe Calf for most frustrating so far, but Baby Ape wins because I have only ever seen one, and it was Poor quality. My Giraffe Calf is at least Common, and I still see them from time to time.)

I also want to upgrade Personal World Destroyer, but he didn't make the cut because I already have Mini Thor, Lil' XT, and a rare Tiny Harvester, which feed my mechanical powerhouse needs at this time. I'd hate to waste it on something that is too similar to something else.

[Syrrie]

My top picks for pets would probably be Speedy, Baby Blizzard Bear and Roo (Curious Oracle Hatchling), because they're three of my all-time favourite pets.

My luck with stones has been very nice and all three of those I've been able to upgrade already

[Emetai]

I wanna upgrade my enchanted broom, spirit of summer and mechanical pandaren dragonling. Too bad magic stones are hardest to find

[Ceathra]

Feline Familiar - for making leveling quick and dirty, I thought my Familiar "Bob" deserved the upgrade.

Mechanical Squirrel - For being one of my long time favorites.

Magic Broom - For versatility in my line-up.

I do have to admit to using a Dragon stone on an Emerald Proto-Whelp since the best I ever found was a poor, but as a straight exercise, the three I listed would be my calls.

[Morgannath]

I havent found any pet stones yet, is there a trick to it?

[Talmar]

My top 3 would be Minfernal, Scourged Whelpling and either Jade Owl or Mecha Panda Dragon.

Probably the MPD.

How funny that you say this as the only 2 stones I've got so far are 1 Beast (used for Baby Blizzard Bear) and 1 Dragon which I used for Emerald Proto-Whelp as the only one I've seen so far and captured was, like you, poor.

Scourged Whelp. I'm tired of hunting, and I've found a lot. Just never a rare. So that will leave more in the world for others to find

So far I've upgraded Minfernal, Infinite Whelp, Harpy Youngling, Crow, Red Cricket, (and a beast and an aquatic I can't remember). I have a Magic stone, I think I'll use on the Jade Owl and a non-specific one for the Scourged Whelp. A little afraid to use it, thinking I'll get that family in my next bag, but sometimes you gotta take the big chances

I have gotten BoP random family stones from grand master dailies, and gotten a flawless non BoP non family specific stone on a random wild pet battle in Pandaria. You also have a chance to get family specific BoP stones for doing battles with any pets in the world, though the higher the level, the higher the chance. So fighting a frog in Pandaria will give a chance at a BoP aquatic stone, etc.

Did that help?

[Adamsavage]

I would go for one that is hard to find, never mind getting a rare. If you can get a rare by simply keep checking then don't do it. I have 2 myself, and I'm saving one for that rare in Felwood, and possibly my Nexus Whelpling.
