really I like this idea we need more weapons that can evolve in to other things. remember how necrochasm worked I never got that gun my self partly cause it sucked buy anyway I think the Kvostov showed work like that were you could turn it from a common in to a exotic. However, not sure how it would be pimped out like exotic perks for it and other things like that. and how the upgrade process would work. But that sounds cool
