I don't think there is anything to fix, it's just a matter of understanding how it works. For example:
- When you look at the tower map, you can see an icon on 8 of the vendors. Hovering over this will denote 0/8 bounties complete. Completing bounties from this vendor will reward power gear, to increase your powerlevel.
- If you look on the map, there is a gold cirucular icon. If you hover over these, it'll show you the same - you have to complete, for example, public events on the chosen planet, 4 gambit games, 4 crucible games, 4 strikes with the same class as the burn....
The biggest issue I think for new players is ineed not knowing where to start or getting the old campaigns to play though. There's nothing to "fix" perse, but they could absolutley give new players better guidance on how to complete certain objectives.
I would stick it out and come to the discord server. There's a load of us playing daily who can give you a run down of where to go and what you need to do in order to progress. Once you get the hang of it, it's pretty straight forward.
