Well claiming that parcour is "realistic" and thus should be easily and commonly done in a GoT inspired game is some serious genre and trope twisting so I guess twists all around.
And you're mistaken, my answer to your question was actually... Yes, but you need specific training to pull it off. Now I'm still waiting for you to tell me why you believe common and easily available parcour is genre appropriate to a GoT inspired game...or is this not so much about justifying what you are (in good faith??) claiming should be in the game but trying to get me to say no, by selecting and using a genre inappropriate trope with a flimsy excuse... "It's realistic" (so is breakdancing... should characters all know and be able to breakdance in a GoT inspired game??) and then hollering gotcha when I don't 100% agree with said flimsy excuse?
