Well I must say, if this is accurate and if MA chose to embed the info that gives you the best chance to loot each item, inside riddles, then i'm all for it!
I think it's a great idea and yes i'm biased. For once, it's not about how big your pistol is, but how smart your brain is! Seems some specific areas/mobs were chosen to carry the items, possibly a combination of both for some items, meaning the odds of just having a lucky hit are dramatically reduced.
Oh and for the HIGH IQ people who can unravel these, please use your brain just those few steps further and DON'T post your findings in a public area please, let those who have the wisdom reap the rewards!
MWAH, nice going MA!
