The ability to pay the vendor for a new selection of equipment

Mah teamates at the same or even lower level then me are rocking flamers and bullpup auto-lasguns and im over here using an autogun from 4 levels ago because its the only good gun that suits my playstyle that the RNG gods- i mean the emperor- was willing to give me. Please give us with consistently sh*t luck the ability to keep up with our friends in terms of cool guns.
