Shoulder charge is still a melee regardless of what column its in, try looking up the meaning of the word.
English

I know it's a melee, but you are comparing an ability that requires 2-3 seconds of sprinting to charge up, dies if you sprint too long (unless you use an exotic), and is a high risk high reward kill to throwing knife. again, if throwing knife would get the same lethality as shoulder charge, all other melee would need to be buffed up as well, which would destroy pvp even further

It had the same lethality as sc before the nerf, just required more skill
