There were times I'm your first video it took you half a mag to kill someone with all headshots, if the level of your gun didn't matter you would have killed them much faster but because it's a level 1 gun the damage was minimal. Just because you are a level 4 doesn't mean you can't do damage to level 28+ because then iron banner couldn't be enjoyed by everyone. They made it to where there is a slight advantage based on armor and weapon strength but not to the point where a lower level 20 still couldn't do well.
