I think there is too many problems for Bungie to even figure out. They obviously are trying (maybe not succeeding), but how can we expect them to find a solution when there are so many flaws, as pointed out by the pages and pages of blogs and complaints? I like you idea of finding the weapons. I would be more interested if that was another game mode option versus changing all the others. It would be cool if all the guns people have equipped are the guns that can show up around the map. People could try out all sorts of weapons too, instead of the same old same old. Seeing other guns perform would also promote players to go earn them in PvE.
