Ok, convolution is one thing... this is just insanity. Most of this stuff involves locations and NPCs that have existed for so many expansions, and some of the stuff is so obscure that no one other than insane lore buffs could have a chance to understand. While I appreciate Blizzard's scavenger hunt, I think next time they could tone down the randomness of it all, and make something that can be fun to solve for regular players without requiring a guide.
