10 Problems With Pokémon Gold & Silver Nobody Wants To Admit
3. The Dark Type Was Underutilised
A lot has been made about how much balance the Dark and Steel types brought to the game, and rightly so. The Steel type proved to be a defensive bastion which made the most of a limited offense to carve itself a wonderful niche in the game as a guaranteed wall against all but the most purely offensive types of Pokémon. But where it flourished, the Dark type did not receive such favorable treatment.
This is not to say it was a bust by any means; the Dark type stemmed the dominance of the previously untouchable Psychic and Ghost types, offering solid moves like Feint Attack and Crunch to a wide array of Pokemon that deterred the first generation behemoths. The problem was that these new moves were better off in the hands of the non-Dark Pokemon who had such wide access to them.
To go all technical on the problem, Dark type moves were classed as special at this time, and derived their power from a Pokémon's Special Attack stat. Most Dark type Pokémon had all their strength invested in the Attack stat instead, making them sub-par with their own moves. Genius. On top of that only six Dark type Pokémon were introduced, five of which could not even be obtained until the player reached the Kanto region and then would not be seen in the wild unless you stayed up until night time. If their appearance was meant to be an endgame bonus, then it should have been refundable.
