“Skill based damage”

Alright I have 35hrs in this game already and it’s not bad, but would someone care to explain how mag dumping center mass with a carbine is not killing someone? And I am not just salty or have a skill issue I recorded it counted 30 hit markers from about 30m and he did not die. Meanwhile I’m getting 2 shot by pistols and insta killed by a shotgun from 57m away. This better be a joke DICE if not, I want my money back.
