I think the definition of "useful" is that it improves the party to invite one rather than leave the spot empty. The opposite is useless, and means that even if you invited the job, the party wouldn't do better.

Usually when people say "useful" they mean "ultimate" or "the best" or "overpowered". That is why so few jobs are "useful".
