>>12808682I can only agree with you on Dark, Rock, and Ice my good sir
But I would replace the other two with:
Bug (Outside of Bug/Steels and Volcarona, they aren't seen a lot, or even used due to rocks and weak offenses. Plus unSTABed Bug is only for a drastically shallow movepool.) And U-turn spam ain't for the coverage, godamn.
Psychic (Mostly neutral defensively, kind of bland in general, easily trappable and NEEDS certain abilities and gimmicks to make them "different")
And I guess an honorable mention goes to Electric (Almost the same as Psychic, only becoming somewhat diverse just recently this gen)
That's just me though
