Okay... This'll be quick and painless. Easy answer to how we can all upgrade our old raid weapons to the next level, be it 331 or 362 (or whatever damage the HoW weapons will be). In the new raid, a token drops from the boss. Similar drop rates, perhaps, to the crux in CE now. This token can be taken to the Gunsmith in the tower. I select him, choose "upgrade", have my 300 Fatebringer, the token, 12k glimmer and as many strange coins as it'd take to purchase a weapon of similar value from Xur (ie...23 for a primary, 17 for special/heavy). Bam! I have a 331 Fatebringer that remains fully upgraded. Now...I want my Fate to be 362 (or whatever), I repeat the process. Easy...keeps people from upgrading every weapon in their inventory, forces people to run the new raid, gives people their "favorite" weapon to remain relevant.
