A problem I can see already rearing its ugly head around is the lack of room to hold on to these weapons. If we are to upgrade and keep these weapons relevant, then there also needs to be room to store these treasures. I know so many people who have had to part with their loot simply because they are at capacity. When you make these weapons upgradeable, increased storage capacity must be implemented alongside it in order for this update to have a meaningful impact on the greatest number of players.
