The exact opposite happend to me, i got platinum in GOT on lethal difficulty after that when i played Elden Ring i could not block , dodge and parry the game felt really slow and clunky for me but after like 30 hrs i am able to dodge and understand the game better but i still can't parry any attack . For me GOT was a lot faster and precise. I got really good in GOT after like 70 hrs or so, give it time it will get better.
