Since Dori's primary role is a healer, her gameplay is undemanding. Nevertheless, players have to get used to aiming her Skill and gaining the most of her Burst. Dori's Burst heals and restore Energy periodically, and it also creates a line that apply Electro to enemies that came in contact with it.
Most weekly boss has a high mobility while Jean's Burst remains in a fixed AoE. This means melee characters can't stay in her Burst AoE to heal. Additionally, Jean also can't yeet bosses, which means her Elemental Skill is also downgraded.
Similar to the issue with weekly boss, Jean is highly limited against world bosses. However, since most world bosses are immobile, she's at least viable as a reliable healer.
Although Dori is a great healer and battery, she's still shadowed by powerful battery like Raiden Shogun, or a better healer such as Bennett. Because of this, Dori rarely shows up in players' Spiral Abyss team.
