>Not only is it directly in opposition to the rules (which grinds my gears, I might be a little OCD)

Having FAQ in opposition to the rules is a very real issue when one of the players has read the FAQ while GM has only read the rules, since at that point they think the rules function in two cardinally different ways.

>I mean, when you slay the demon lord and loot his shiny +5 mace of whupass, you might wonder where he got that thing when none of his kinfolk can create it.

Outsourcing, duh. Bet you that mace has MADE IN CHINA TIAN XIA inscribed on it in eldritch arcane runes.
