I'm fairly certain that victory rank simply affects the chance of getting a drop in the first place. It's entirely possible to get the rare Tachis, Yaris, and Naginata from World 5 - they're just very very uncommon. In any case, it's impossible to get a S rank in World 5 anyway (with the exception of winning an Ikkiuchi duel), so you've already maximized the chances of getting them.
