I like it. My only problem with taking old guns with you was how to make it a hard choice on what gun to upgrade...having the last boss in the current HM raid drop the item to use as the token is awesome and still makes RNG reward/punish, you still have to grind both for that token and then the current mats. Thoughts on whether or not you should be able to swap the raid perk(VOG vs Oracles/CE vs Hive Majors...). I feel you should be able to when you upgrade the gun, but if/when you do you lose the old perk and only by using same upgrade token can you change it back(just the perk, damage would not matter due to dmg caps vs levels).
