A guy in my guild wanted Zin'rokh. He farmed Kalimdor to get his archaeology up, and saved his troll tablets. He even had a small stockpile of troll fragments so he could power through a few solves as soon as he hit 450.
Well, his VERY FIRST TROLL PROJECT after he hit 450 was Zin'rokh. Now he's got 38 troll tablets he can't sell and all the other tanks in the guild hate him.
