Easily implemented level 20? Most tabletop game masters can’t implement a level 20 game without the limitations of a video game. They invariably wind up cartoonish, broken, and unbalanced. There is a reason there is only one official adventure that even ranges up to 20. Balance may not matter to you but It does matter for a game.
The performance improvements alone are insane. I’m playing on PS5, just got into act 3. I turned it off on Tuesday a little frustrated by how the game was running inside of the lower city. Turned it back on after patching and everything is smoother than the entire rest of the game has been for me.
Also, being able to access all party member inventories is a game changer.
