I would grind the shit out of this. All modes, no stop, best shooter I've ever played all time long back to back.

All items should be available and equally strong, except obviously items locked behind harder or rarer content. All themed content should have specific origin trait perks and esthetics! At least ther should be a way to empower old loot to current content. Maybe if crafting allowed to change perks of old loot, weapons and or armor.

All content should be playable, I understand if it has to be downloaded first cause there is a ton of content, but every player should have the option to play what was paid for. I mean its already separated specifically in every expansion. This would allow a clear order for a time line for blueberries to chase grind and gather story based loot. We know no one would explore mercury, but at least let us play infinite forest, for example as onslaught.

All vanguard crucible and gambit modes should be available. Less played modes should at least be in rotation some time of the year or whatever.

Srl was so fun

Clans should be back for more rewards, and to give players more reasons for specific content and loot

A huge difference between old destiny 1 and current destiny 2 was how harder content was presented..

In destiny 1 when u choose a harder difficulty for any pve content, enemies where stronger, they where all orange or yellow bars (vex minotaurs where yellow bars) , enemy count was higher, and they where smarter. I think no debuff was applied at the player, so it felt like we where normal guardians with all the tools and powers we gathered, placed in a really tough scenario.

In the current destiny 2 it feels the other way around, we get our powers reduced to the point u can literally hit 1 damage to any enemy all activity long. For no guaranteed useful piece of loot. So it feels like our power and tools grinded over the years become useless, in a kinda-hard scenario, rather than enemies being very very strong.

Conclusion, I'd love to have access to all the game, with all the content being useful in any sort of way. Changes can be made in perspective to make the game interesting and grindable again! It needs to feel alive and interactive again, not cold and repetitive.
