Lian, contrary to most damage dealers, is food for most tanks. An aggressive tank like Fernando or Ash essentially have her on a guaranteed death timer the moment they press F, and defensive tanks like Barik and Ruckus outdps and destroy her.
Lian can deal massive damage with either lessened or zero need for aim. Her ability to spread damage is massive giving her inflated damage and credit scores, but her DPS is awful. If you are a damage dealer, you'll have to make the tank end her life.
