Parkour and Free Running

I'm hoping for a revamped movement system while running, what if Jason and Lucia you could learn to climb to places in a Gym or a specific area and help you trough the game, maybe specific free running mechanics wall running and the ability to travel trough the map in a new way. We saw in San Andreas and GTA IV the ability to grab ledges and vault objects but it was lost in GTA V with that poor physics and jumping towards ledges would lead you to your demise but what if we could perform a wall-run or tic-tac-toe to reach different places in a setting like Miami full of structures. The mods will eventually give us that in the future on PC.
