>>51301893I didn't combine them, I just removed Dark since thematically I thought it was pretty weak. It's just mean normal type. Most of it's members work far better as ghost or normal type. Offensively it and ghost are nearly interchangable, and defensively the type was a kneejerk reaction from gen1. Steel type and ghost/bug pokemon not sucking anymore is more than enough to balance psychic, an immunity was overkill.
Of course I am slightly a dingus who combined ground with rock and assimilated fighting and flying into Normal-type, so don't take that hottake too seriously. Pokemon leans too heavily on types and reducing the number while adding more move/ability variety would make for a more fun game imo. Less different flavored boltbeams, more dumb gimmicky 4D chess bullshit like reflect-type, ion deluge and soak.
