It is something that is really needed. With the system forcing people to stand in line. And people wanting to do double line because of it. People have to aim between the heads of people, sure the 2nd line could do a stacked line formation positioning themselfs in between behind 2 of his comarades. But why not, when aiming and standing still with Q you do with the left leg a step to the left. and with E a step to the right. So people can do a proper double line, without aiming weirdly or shooting your comarades in front of you.
