>>19280423It's not a good offensive type either
>DarkDark isn't common, but it's gotten more prevalent competitively now that it's neutral to Steel and Knock-Off got buffed. However, the most commonly used Dark types are Bisharp and Mandibuzz, both of which have a second type that resists Bug.
>GrassUseful, but uncommon in competitive play. The only Grass-types you're likely to see are Ferrothorn, Breloom, and Venusaur, all of which have a second type that resists Bug.
>PsychicUseful. However, Psychic types are generally pretty frail anyway, and the buffs to Dark and Ghost this Gen make them generally more attractive options for dealing with Psychics.
>Fairy should have resisted FightingBut it does
>>19280503Fighting is an excellent type because it has excellent offensive ability including the ability to hit Normal and Steel super-effectively, and only was weak to Psychic and Flying, the former of which are generally very frail defensively and could still be hit for massive damage despite resisting, and the latter has been routinely screwed by Stealth Rock.
Fighting is up there with Fire, Water, and Fairy as some of the best all-around types.
