Can Luna have high DPS and Elims?

EDIT: Thank you everyone for the explanations. I understand now.

I know Mantis is the Go To for a strategist with high Elim potential. Why isn’t Luna also considered a high dps? I haven’t played her much but thought she has has a 3 hit burst headshot potential? Why do people gravitate towards Mantis who has Projectile and not Luna for Hitscan?
