Favorite Pet Teams

[Valentina]

I'm looking for a list of pets that would advisable to level. I'm starting on this list
http://www.warcraftpets.com/wow-pets/top-twenty/
Are there more needed? I still haven't been able to complete the Celestial Tournament :/

That's a good list to start with.
You want to level anything that's a double threat, meaning resistant to a typing, and then also super effective VS that same typing. A good example is Kunlai Runt which just demolishes critters.

I'll also recommend
Snail (for fighting Elementals)
Swamp Croaker (Great with bubble, good against Undead)
Jade Owl (Must have against Aquatics)
Emperor Crab P/P (Hard hitting Aquatic that can take hits)

I personally feel as if the list is based on hype/appearance rather than their usefulness. Most pets are useful in battles. I would recommend leveling pets that you feel strongly attached to.

If your goal is to beat the Celestial Tournament i would recommend this guide: http://us.battle.net/wow/en/forum/topic/10195019513?page=1

Shale Hatchling
Spider
Parrot P/S or S/S
Grub

Fel Flame
Scourged Whelpling
Any fast Flying pet with Stampede/Flock.
