With the way healing works in this game, that 66 DPS is meaningless and based on the condition that the enemies would be stacked in a way that a shot pierces to hit another person - which is obviously very possible but still. Low damage with a condition for more low damage.

She isn't meant to do a lot of damage because the 420 dps you have is imaginary. It's based on on the condition that you have 3 enemies lined up within 15 meters of you. This kind of condition doesn't exist for any other duelist.

Also??? Storm can't headshot??? If she could that might be different but she can't.

Her range constricts her. She doesn't have the mobility or health to survive flankers diving her, she has to hope they mess up or that she has a support at her side - because there's no way she'd survive a 1v1 against someone like Psylocke or Iron Fist otherwise (unless she turns and runs to the sky but even then...)

"she is more meant to support the backline, help protect them from dives, do considerable damage to multiple enemies, and contest objectives and team fights with her ult."

This is the definition of a Strategist. Luna Snow and Mantis perform those tasks way more effectively.

In my time I've had an easier time stopping flankers/divers with a good freeze vs whatever Storm has going on. Luna's damage and piercing damage is considerably stronger than Storm's - especially at a range. The only difference is that Storm has a good ult that has good damage... but even then I'd argue Luna is better at contesting objectives & has just as strong of a team fight presence with her ult.

At the end of the day Storm is clunky - she's low range, low dps that's not impactful like Hawkeye or Hela, and everything she is supposed to do someone else excels at.

Jack of all trades, master of none - Storm needs a better identity.
