I think a major reason why the Legacy is a really bad faction on it's own is the fact that it relies heavily on being a one-trick pony, most of their powers are only useful once and they aren't cut out for long battles. In the first few rounds, the Pikemen relied heavily on trying to kill as many people as possible because when they use their pikes they're useless so during the final moments they would rely on overwhelming numbers to punch their enemies to death
