I like the idea of backgrounds, but they could be more interesting. I encourage my players to create their own if nothing jumps out at them from the phb. I don't like the traits, bonds, etc. being placed on tables, as it encourages players to pick off the list or roll. Examples are great, but don't need them on tables. It's probably a pain for designers when new features are added that require tables of traits. I really encourage players to create their own traits and write them using their character's voice. It's fine to pick a few from book if stuck, or see one that's perfect. In my game, it's also okay to leave traits blank for few sessions, until the character gels. I'm also thinking very seriously about having 3 or 4 traits, plus a flaw, rather than the split into ideals and bonds. They overlap anyway, and it seems a little artificial that all characters have one bond, and one ideal plus 2 traits.
