Some people don't actually need to use support expeditions for clearing World 5. However, most of the time it's to compensate for World 5 quests (such as Nishimura Fleet and the Mikawa Fleet quest where you need to S-rank the Boss Node) since when you're running those fleets, chances are you're sorely lacking in firepower for a proper S-rank due to LoS requirements or routing RNG.
