In my opinion, there are roleplays where a history section is called for; where it's thematically significant and will pertain more to the character and the story as a whole. However, in those that don't really need a history (which are often the majority), I prefer to have more of a lifestyle section, where you list a character's habits, profession, significant traits, etc. Just small details that bring the character to life more than writing a history that will be referenced maybe once IC. If anything, the history can be just that - references towards a character's past escapades within the IC posts, and sometimes historical reasons provided for anything out of the ordinary in one of the other CS fields. If need be, it can always be supplemented with the requirement for a Sample Post, as opposed to what I consider the Marmite of a CS (you either love it or you hate it).
