No, it would take more effort than it's worth, and the old weapons would make everything new obsolete again because they were OP. I like that they took the old areas and made new missions in them, that's a much better use of the assets from the old raids, and doing more along those lines is a better idea. It also just makes more sense. Like, wait, didn't this huge ship roll in and wipe out the awoken because we killed Crota? Didn't I crash his funeral in this exact spot?
