Actually I'll say that this change is by its very definition a time sink. Now in order to use an assault rifle, lets say, in new top-tier content you have to acquire another top-tier assault rifle. Your old top tier assault rifle isn't good enough anymore, and not for anything to do with strategy or gameplay but simply because bungie decided to move the numbers of the new content just a little higher. Therefore, in order to stay current with Destiny you have to invest just as much time into equipment [i]now [/i]as you may have done a year ago. So why did you bother in the first place? Why not just stick with blue gear early on and invest your time into when it mattered more? See. waste (and this waste is going to keep occurring with every major add-on unless Bungie changes directions again). Granted, there's the opportunity to play with a new gun instead of an old one but [i]do [/i]keep in mind that without planned sandbox obsolescence we could have had that anyway. New guns could have been added [i]along side[/i] old, building up a larger collection of sandbox elements for players to use as their preferences dictated. That would have also allowed old staples to live on indefinitely as niche choices, preferable in some circumstances (because of their unique handling characteristics) but not all. That could have made weapon choice more interesting, and increasingly more interesting as time went on (finally justifying some part of Bungie's approach to Destiny). But no, Bungie wanted to enshrine grinding.
