How about if you also have the 3rd edition army compendium and a bunch of the 4th edition books,
And how about when you have as many of the old books and versions as you can and are searching like some crazed lore junkie for older fluff! More versions! Both so you can have more tasty tasty knowledge but also, so have a reference to point to when someone gets out some daffy new idea like celibate Witch Elves*
Witch Elves are about as far from nuns as it is possible to get. They're (the old books, not the Witch Elves) also useful if you want to show someone male Sorcerors when they say there aren't any in the fluff.
I'm not sure what this habit is called, Lore Addiction maybe, but it's probably a sign of too much Warhammer ... background
*For those of you not acquainted with old lore from the time when dinosaurs walked the earth (Slann?), Witch Elves used to lead the Dark Elf armies in what, on a family forum, we'll call "post battle celebrations". Any male children born to them were trained as assassins if they survived being chucked in the cauldron as an offering to Khaine, and any girls got raised as Witch Elves.
Well, I guess it might be an extra incentive to win for some of the troops?
