>>26687716psychic could be cosmic or astral, I feel like Astral fits better though. Relates to both the stars and psychic paranormal shit.
As for dark, I don't think it's good to merge ghost with it. Dark =/= spiritual shit, spirit =/= astral shit
I think it's good to separate dark and ghost due to dark being more of a way of acting, where ghost is a state of being. Dark is fine how it is.
Fairy is something that does need to change, and I think light should have existed back when dark was implemented. Fairy encompasses both actual light and goodness/morality, it also stands for all the shit in fairytales like courage and chivalry, fantasy, triumphing, ETC.
But just like Dark can encompass both literal blackness, void and evil, Light can also do the same for whiteness, light and goodness. Fairy is odd just because it has that whole "fantasy" thing going for it, but again fairies are more of an actual creature and not a "type".
Bug needs to go away.
Bugs can be comprised of other basic elements soooo.
