Have you ever seen Monty Python's Holy Grail?
I want that bunny.
If I had my way and I could get any one pet class as a tamable class it would be the rabbit. Sure, there are no non critter rabbits in the game but they can make some. And if anyone says but a rabbit can not really be an attacker then they have not seen the Holy Grail.
Check it out.
I would never ever ever ever use another pet again if I could just get my killer rabbit. Do you think Blizzard takes bribes? I'd pay.
