I heard some rumours about Blizzard removing the mount from Stratholme and Zul'Gurub in Cataclysm so I'm running those intances as often as i can trying to get the mounts.
Got the tiger out of the 3 so far and I'm up to 41 Baron kills. Hope i don't reach 100 before my mount drops!
I'm not sure about the Raven Lord yet because i need a druid to summon the boss for me. It's one of the coolest mounts in game so I just gotta find a druid so i can farm the mount. But the mount will be available in Cataclysm so I'm in no hurry for the time beeing.
Would love to get Mimirons Head and the Time lost Proto Drake but i gotta be extremely lucky to get those two.
Any suggestion on other mounts i can go for?
