Why nerf this?

[Encryptions]

We'll be doing a +15% sustained Haste with this pet.

Ok ok, 15% haste with the other stats sir sir?
Rogue gets arc lovling as a maxed out pet with absolutely everything a rogue needs. Crit, damage stack, damage reduct stack, and mana ignore.
Mage gets many pet variations based on its type of game play.
Warrior gets 0 actually warrior type pets. By warrior type I mean: Dmg stacking, Dmg redu stacking, haste, and crit chance.
