I'm very proud to say that my guild has gotten the Zul'aman bear mount speed run down and under control. We've gotten two bear mounts now and think we can comfortably churn out a few more before the 3.0 patch drops. Zul'aman is a very fun instance and the speed run keeps it challenging even for T6 geared raiders. It's a great feral druid run, too; I get to tank, heal, and DPS all in a single raid.
I'd like to give a special shout-out to Cassytha (and Pepped, before) for organizing our weekly ZA runs. Took us about eight weeks of dedicated attempts to get it down to where we could do the 4 bosses in 45 minutes.
