That's a great point actually. Everyone always states that something is normal or doesn't occur in Mmo's as if Bungie are forced to follow the exact same formula. I thought that maybe old raids would be a good introduction to raids and stuff for new players when TTK came out but I seriously doubt anyone new is looking to do the old raids since they can just hit 40 and get ready for King's Fall. I understand why the raids themselves are untouched, in terms of story/world progression it doesn't make sense that they'd be updated since they were destroyed in Y1. Aetheon is dead, the VoG is empty as shown in the paradox mission; Crota's dead and his invasion has failed, Hive are no longer amassing on Luna. The Prison could be updated with different bosses w/o breaking story/world progression but with The Queen dead/missing collecting prisoner's is pointless for the Awoken. What I think needs done, so there's incentive to do the old end game content, is create an avenue to turn raid rewards in to rep or something (outside of breaking them down for parts, glimmer and motes). Create a new faction that is interested in the 'relics' of the old raids. Have armor sets that resemble old raid sets available through purchase & faction packages. Introduce weapons with Vex & Hive burn abilities that resemble old raid weapons. There are ways to keep old content relevant w/o breaking story/world progression. TTK end game is worse than when the Destiny was released. There's 1 raid and NF's are pointless.
