I do miss the random rolls and weapon leveling a bit. Even if weapons are static it still would have been nice to have to grind the weapon a little bit in order to level it and unlock perks. It was a good way to master the weapon, and it kept getting better as you unlocked more perks, thus making you even more efficient with it once it was completely leveled. Plus it kinda made you use weapons that you really has no interest in using, and perhaps discovering you actually prefer it in some situations over your favorite. The static rolls wouldn't be so bad if there was a heck of a lot more weapons. But it sure is annoying turning in engram after engram only to keep getting the same weapons you already have and probably don't even use. Bungie should have introduced a new weapon subsystem, such as something between legendary and exotic, which allows rerolls under certain circumstances.
