Invisibility

This is the only pet that has this ability.  At the end of Two rounds after activated, you will be unattackable for 1 round, 4 round cooldown. So this makes you unattackable 20% of the time, giving your enemy 2 round notification of what you are doing.

Defelection

This ability is available on 5 pets.  Ability always goes first, blocks all attacks for that round 3 round cooldown.

Make sense to anyone?

How is it certain warcraftpets.com members have both the horde and alliance version of these pets?

They spawn at 6:30pm server time, did a complete loop at 6:25 nothing, just after 6:30 almost every spawn point

Fortunately I have 20 characters level 80 or higher. I positioned each one at a different spawn location. All but one character are on the same server,  I currently run two accounts. I then cycled through my characters simultaneously on both accounts. After approximately 200 logins in two hours I  saw 5 of these, 3 already engaged by another player and two that I captured. 

Best pet I have found for safely leveling a level one carry pet.

My server I have seen a ton of gold and jade, but not one crimson
