I agree, partly. But really there's only so much you can do with a gun. The most obvious ways of creating variety are messing with rof, how well they handle, bullet count, impact etc etc. This is what Bungie borked inistially by giving us weapons with base stats so good there's no wriggle room. Why take a low impact, high rof autorifle when we already have high impact versions? Why take a new fusion when the old ones one shot ppl from across the map?
