I now have Zarakh at level 70. At about level 64, Blizzard changed pet leveling to be faster. Argh. Oh well. Should have waited, but he's still nice at 70.

I have seen more Alliance RUN FROM ZARAKH in PvP than any other pet I've had. The black spiky model and the scary hissing sounds seems to freak people out, especially since hardly anyone has this pet at level 70, especially Horde.

I get compliments on him all the time and people wonder where's he's from, particularly  on the Horde side.

I have him pimped out with stamina and armor. He lasts forever. Great tank pet. Doesn't do as much damage as my Kaliri bird from Skettis, but I still enjoy playing with him.
