So this is just a thought but does anyone else think that the psychic and fighting types deserve immunities like the dark type. For instance have dark immune to psychic, psychic immune to fighting and fighting immune to dark. It could be like psychics can protect themselves with like barriers and so fighting types have effect. For fighting types it could be like martial artist tend to be spiritual and very strong willed therefore darkness has no effect on them. I dont know its just a something i thought would be pretty cool.
