Crothian said:First, what is a typical world? We have Eberron, Midnight, Scarred Lands, Greyhawk, Oathbound, and many others. I honestly have no idea what a typical setting is.
Ignoring that, the PCs are where the game is focused on. I have no idea if cure spells are being used on miner, fishermen, lumberjacks, etc becasue that never comes up. So, it's adventurers that get the most.
Why assume it's the adventurers when they constitute a small minority of the population?
