is there a "correct" way to play emma?

just got off a game in comp, where i was threatened to be reported bc i was "playing emma incorrectly"

i am at centurion proficiency with her, which came from a combo of qp, comp, and doom match (to increase my survivability and make my kills quicker). i have a great win rate in qp with her, but is it possible that i'm playing her "wrong"?

also, i checked the guy's profile and he lost any games he played as her, but my question still stands
