I haven't played Baldur's Gate or Planscape Torment so i don't know if they had puzzles like this so maybe i'm wrong, maybe "oldschool RPG" games were similar to Divinity.

I'm talking about something else. For example i love Portal and other puzzle games, i don't hate puzzles, it's like making a great FPS game and putting driving missions in it with horrible driving mechanics. You don't need to do that. You don't need to put crafting system if it's not good enough.
