I'd like for exotics to be able to come forward with us as Destiny grows, but I don't think it should be as simple as ascension was, I believe we would feel much better if we were able to sacrifice other weapons to slowly upgrade our exotics to a usable level, and perhaps build a quest around redeeming former exotics, where we have to gather light(motes of light or some other form of light added for this purpose), a specific material based on the gun, and a quest item that has to be found on a specific planet or mission, until finally it is brought to the gunsmith, or perhaps even the speaker because of the light needed.
