15.5 secondaries are still useful in a variety of situations. Ships that can't use artillery spotting: CLT, Yuubari etc., or ships that have other equipment like Searchlight, flares can opt for secondaries instead. Maps with emphasis on Night battle like 5-3 or Event maps can make it more optimal to use night battle equipment (and secondaries).

They are also useful for farming xp when you want to have more predictable damage cut-in/mixed on ships.
