I understand that you want content to last all season, but the current system ruins the game. There is no reason to play day one because you can only do 1/9 th of the story (if that). You can't even efficiently farm deepsight weapons until week 4 or 5.
So this isn't just complaining, here are some changes that I think would work better:
Content to have right off the bat:
- The whole story with access to challenges for the upgrade table so we can do it at our own pace vs weekly.
- The dungeon, trials, all exotic quest
Weekly rotation:
- Crucible game modes including Iron Banner
- Nightfalls
- Seasonal events
