Darkness is an annoying Status Ailment more because of its permanent nature than its effect. While half accuracy is problematic for front-line fighters, few Monsters have the evasion to really take advantage of it. Darkness causes more problems for Monsters, especially if you're already evading half of their attacks. But as a permanent Status Ailment, a Character afflicted with Darkness gains no progress after a battle. Fortunately, Esuna 1 is enough to cure Darkness, even curing multiple party members when used outside of combat.
