I think the idea to have a Lord accept the commoner's oath to become nobility is a great piece of role-playing that wouldn't make it functionally more difficult to become a noble if that is one's goal. I've been playing an adventurer for a few months in-game and have a couple recommendations. I feel like the process right now depends a good deal on luck, and so will vary between players. However, I think the time and effort currently required is enough that it seems like a real achievement but not so much that it isn't worth trying.
