I don't understand this choice in the first place, and even less why to force people to add sub names instead of dub names when creating an article. Sub names aren't official, while the dub names are. I think it would be better to add the dub names forst and the add the sub name. It'll be way easy if we need some information, especially since the games and the english patch of Galaxy is using the dub names (which is a way better choice than the sub names).
