Just to add my two cents here I don't know why they would bother upgrading the weapons, it is afterall a mmo now following suit of other mmos old hear become irrelevant and just a vanity peice I mean take wow for comparison they have raids going back ten yearsvwith loot that comes no where near end game now an they haven't gone oh we better make this inline with the latest update or people will cry, at its heart destiny is a mmo and with that comes certain inevitability this is measly one of them, I mean all I can see them doing in future is some kind of tramsmorfer that replaces the looks of x with y while keeping the stats of x.
