As this is your first mmo, it's understandable that you think this way. I love my current guns to pieces. I did in the vanilla armory as well, but I'll be dismantling my non raid weapons after ttk comes out because you have to adapt. In all honesty, the only raid weapons I'll keep are the vog ones. Once I get the crux, Crota stuff will be gone for the most part. You have to put the guns to rest. It would be extremely boring if we took something like a shadow price or a vanquisher through all the ten years they have planned for this game. That's why we won't be able to ascend. They want people to broaden their horizons.
