Just to complicate matters a bit; In the future you’ll also have to consider how different backgrounds play together and what they might bring to the team outside of combat. Putting a bunch of nobles together with a bunch of beggars and vagabonds may lead to social conflict as nobles refuse to treat beggars as equals, and having a Hedge Knight means that he’ll solve any potential disputes involving him the bloody way. An old swordmaster can make a good teacher, but age will also eventually catch up with him. Those things are hard to quantify, obviously.
