Skill based match making

Id be more worried about skill based damage.... purely anecdotal but some games i clean up other games my bullets hit 10-20 times tracking right on a person, Shot gun point blank range etc and it feels like im shooting nerf darts, i die in 3 hits in a frame but ill be shootin someone for 1-4 seconds or land a shotgun pointblank into a chest and its done 20 or less damage... I can see the hit, i can see the hit marker, i can see the multiple headshot or multiple hit markers... They're still alive and im left holding my **bleep** in my hand because the damage that should have killed them 5 hits ago hasnt gone off. had one really got hit detection game, landing most of my shots went like 63-10 or something... next 5 games next to 0 damage, better tracking, just nothin... watchin myself roll 20bullets into someone for 50 damage is very frustrating,
