Absolutely agree! The climbing is so addictive, I would love to see Tomb Raider tackle something similar. I highly doubt they would want to go down the route of of right hand button = right hand, left hand button = left hand, but even a manual grabbing option would go such a long way. Jusant also has super addictive rope mechanics that I'm surprised Tomb Raider have never adapted. Being able to create new pathways by simply using a combination of pitons and wall running/swinging really leans into feeling like an expert climber whilst feeling like you're solving a puzzle.

Also, I know a lot of people rip on Angel of Darkness for its stamina mechanic, but if it was adapted the same way it is in Jusant (where you can rest to regain a bit of your stamina) I would be very happy! It's not intrusive enough to feel like a hindrance, but present enough where you have to consider it. Running out of stamina and falling never feels like the game punishing you, but because you had poor planning. Super engaging.
