I got many of my crucible weapons from weekly heroics and nightfalls. I understand they have different attributes.If you play enough PVE you get the same things over time. Last time i checked the vanguard quartermaster had over a dozen which are comparable with the crucible quartermaster. the only thing that are different is faction weapons, and they are all about the same any way you slice it. This inst that big of a deal and its a non-issue.
