So more than half weapon kills are primaries and of that 1/3 are folks using their newest drop. Sounds spot-on to me. The matador archetype is a different story though. I am of the belief that shottys should be more of a range vs impact trade off, instead of rof vs impact. Make the longest range ones require some precision, like chaperone. Make the hardest hitting ones absolutely destroy active supers at ultra close range but lose steam quickly over a few meters, so each type has a most effective range.
