I am liking the Vanilla LMG. I know people say not to use it but, I really don't know what else to use. I have always played either a support or designated marksman role. I like hard hitting weapons because I rarely miss a head shot or someone behind cover. When I looked at this chart it showed only two weapons having high velocity ammunition upgrades (chart). They were the Gauss Saw Families. Other upgrades were not available on the GD-22S and others. I am confused I guess. I don't know whats good for my play style.
