Personal travel suggestions with endgame

Hello developers,

I really enjoy PoE2, but I find myself losing motivation to continue playing towards the endgame. I'm not particularly interested in farming currency for real money or constantly crafting and reselling gear. I'd rather focus on getting stronger as the game progresses or achieving specific rewards.

1. I suggest adding a Paragon level system similar to Diablo 3.
2. I also hope the developers can create mechanisms to encourage team play, as playing alone for extended periods gets a bit boring.
3. Additionally, I hope you can optimize the game for lag, especially in high-level multiplayer maps at the endgame.
4. I also suggest reducing the complexity of the terrain, making it as flat or linear as possible.
5. The art style is rather dilapidated and corrupt, but could you consider adding more elements that contrast with it, such as those with a legendary and sacred quality?

Thank you very much with respect :)
