Well, you were in a team with potatoes, so don’t be so hard on yourself.
Without the 6th sense perk you are going to run into traps or waste bullets trying to guess where they are.
As ft you need to learn to play smart and stealthy sometimes. I have created so many builds that rely on strategy rather than damage.
My latest build even has a silencer on the sniper rifle, no yautja bane, or specialization that ups damage. That’s when you find out who is skilled and who merely relies on op builds.
