Water, Fairy and Steel are very good, honestly outright unfair. Trying to fix past broken types just created most absurd ones
> Water
>> only two weaknesses are the type with zero defenses and one whose coverage is a basic requeriment. Then it hits well to everyone.
> Fairy
>> weaknesses are two types nobody uses offensively.
>> Inmune to one of the most OP types before you
>> so powerful that your competitive pokemon don't even min max stats
> Steel
>> resists like half of all types
>> weaknesses are very common, but only one of them actually resists you and they can get rid of with a mere earthquake
In the case of Steel and Fairy, its combinations are also powerhouses that are absurdly strong. Seriously, they're just too good.
What the heck was Gamefreak thinking with Steel type? And on a lesser level, fairy and...water.
