You have a lot of great content in this game that becomes obsolete after a certain level. Considering the fact that most people level to 40 in a matter of days and then spend weeks or months grinding endgame content, potentially awesome content like the Prison of Elders gets left in the dust, and that's a shame. I'd love to have more things to do that will actually help me progress and provide a challenge beyond strikes, events & raids. Destiny is loaded with content, you should really consider update the old stuff and keep it relevant. It seems like a relatively simple way of keeping people playing without actually having to add new things.
