Light type makes zero sense, as does giving dark types another weakness.
You already said this in another topic and I already pointed out that Dark IS getting another weakness if the leak of the day is true: Dark is allegedly weak to Fairy.
Besides, Ghost is the type with all the shadow moves. It's the one in bigger danger of a Light weakness.
And what doesn't make any sense to me is why so many people seem so convinced that a type that exists in plenty of other RPGs makes no sense. >_> --- Creator of Jay's Journey (see quote!) "It's not ten years old! Therefore, it sucks!" - Nostalgia whores everywhere
