@OzzLink yep, me too. It is like everyone is wearing armor and a helmet.
I was using the PBX-45 and it took 10 rounds to kill a guy, all hits from fairly close range. Then right after that, I am hit, then instantly dead without any chance to react to the enemy fire.
They really need to consider tuning all the TTK down to the point where the fastest weapon is not killing faster than the server can update (server tick rate). Right now too many weapons exceed that threshold. With lag comp and aim assist, the server is predicting deaths instead of waiting for the truth data to come in from both sources.
