Sword of Spirit
Legend
I had the same thought, though it's a bit odd that the functionality of Soldier, Noble and Folk Hero are all very similar (able to request food and shelter, essentially), but just the people that will respond to such a request are different per background. I like backgrounds, and understand that they're more about role-playing than gaining an in-game benefit, just wish there was a bit more variety in the main feature, and, unlike the hermit, were all of about the same usefulness.
I actually kind of like the pattern. If background features tell you where you fit (or used to fit) into the campaign world, it makes the most sense for them to provide those sorts of benefits. Theoretically, anyone could achieve the same benefits during play--you just start with one for free. Not a big fan of this "you know a secret" sort of thing. Although I suppose it's something anyone could develop in game, as adventurers are prone to learn things other people won't know about fairly often.
