Recorded Jun's deathknight Tirel and my balance-spec druid 2-manning Sethekk Halls for the mount. Mind you, this is our 60th-something run for the Anzu mount and it is just not dropping!
We figured since it's like a .1% chance to drop, we would expect to get one measly mount by 100th run right? RIGHT?!? Or there is seriously something wrong in the system.
At around 1:52 in the video, Tirel gets pushed back from the mob and aggroes the other mobs in the room, then I stupidly hit my AOE starfall and aggro an extra mob. Just brilliant! Luckily we only had one fatality during that encounter and it wasn't me!
Most of the mobs in Sethekk Halls are of course avoidable at level 80. If I had better gear specced as feral druid I could effortlessly run this instance by myself every day at reset but I'm stuck as moonkin since I have better gear as a moonkin than feral =P
We used to run this instance along with Magister's Terrace for the white hawkstrider mount and for the tiger mount and raptor mounts in ZG religiously like every week or whenever the instance resets, but I think we've pretty much given up hope at this time. We still manage to run it every few weeks per month so they will eventually drop!
Will post up the ZG mount farming video once I edit it.
