I personally love games that allow you to use any weapon. I've always felt that class specific weapons ruin and limit character personalization and diversity. I would say that supers are our class weapons and it shouldn't go beyond that. The idea that you can't use a weapon because you're not wearing the proper outfit turns me away from certain RPGs. I used to love the original Diablo because you could pick up anything and use it. When 3 came out I instantly lost interest when I learned you were restricted to a weapon class. I understand it wouldn't be limiting to that level in Destiny, but it would be limiting none the less. And imagine the hurricane of balance complaints that would follow.
