Grats on the new dino!
On the first week of cata, while I was waiting for my cata disk to arrive (couldn't get the digital pre-order thing to work) when the wotlk zones had virtually emptied out, I decided to level some new pets on my two herbalist hunters in scholazar. Mainly just because of the herb spawn frequency but it was certainly in the back of my mind that I might run across Krush... sure enough I found him with my NE up near Shango on night 1, and then on my BE out near Farunn on night 2.
He didn't cast fear either time (not successfully anyway - didn't check my combat log)... but even if he had, at lvl 80 with Tame Beast on a 10 second cast (less haste) and 0 focus cost, I doubt it would have mattered.
