Neither of your points is convincing imo:
1) You don't need more epic loot after the game is over. That's how a game with a start and a finish works.
2) And again it's a game with a start and an end.
You basically want a neverending game. That is just not the focus and the idea of this game. This game wants to tell a story and and offer a certain "closed" but well crafted experience.
If you want to change or expand that feel free to make a mod. That's why Larian offered mod tools for free. But don't expect Larian to change their vision and idea for the game just because some people might prefer another experience.
