The Question of Aim Assist

Yet I'm continually told people cannot cheat on console. That last round? Four players out of 32 killed me. I died 7 times between them. All of them were console players. All but one of the deaths was a headshot. Multiple times I'm shooting them or someone else for nearly three times as long, and I cannot get a kill, while they are firing one shot. At one point I flanked behind, didn't shoot, didn't do anything to give away. They instantly knew I was there without any scanning. Bang, headshot. Crossplay completely sucks the fun out of any round in this game because it skews so hard toward someone using aim assist. To the point you can blitz them, and they won't die. Something that frequently happens is players getting to about 15hp, and then nothing will connect with them. I've even stopped shooting, then started again, and it still won't hit them. Dead on. Its like they're suddenly repelling damage at that point.
