My favorite rare mount story is probably getting my Azure Drake from Maly 10. I'd gone in there for the weekly not knowing they had changed it with H Oculus/blue drake. We killed it and I saw the Reins of the Azure Drake. My eyes popped out of my head, and I opened my bags to see if I had the gold to buy it off the winner (My dice... ohhh, my dice /sadface). We roll on the drake, I of course lose. So I whispered the winner I'd buy it for 20k. He told me he had already accepted an offer of 15k. I raised my offer to 30k. After a bit he agreed and we met outside the instance. Little did I know, a guildie had been in the instance on an alt in another guild and had been trying to buy it for me knowing I am a hardcore mount collector. /shame
