The only item ever in this game that I spent so much time thinking about, wanting to get...looking at...checking out in my old item-loot-pooling mods. [The Skull of Gul'dan]
I joined the guild I was in around when they were starting SSC/TK, but other members had been around since Karazhan,Gruuls/Magslair and had A LOT more DKP than me. I watched about 5 other people get the [The Skull of Gul'dan] before me. Believe it or not, every-single one of those people quit the game a week or two after getting it.
We cleared BT/Hyjal very very early on (top 50th at least world kill) So we had about 50+ weeks of farming Illidan. In those 50+ weeks we had got 7 glaives (3 full sets and 1 off-hand , and like 15-20 Memento trinkets. The healing memento trinket shared the same loot-pool with the Skull...so every time the Memento dropped and no one needed it I died a little inside.
I was in-line for the Skull for about 6 months before it dropped again. I had 100% raid attendance and my heart would race every time we were about to down illidan each week. I managed to get every-single best in slot item for my mage, I had every other bit of illidan loot, every bit of archimonde loot for casters, EVERYTHING except the skull for so long.
And to think I simply vendored it a little after WOTLK without even giving it a second thought
