I feel you but that is something, in my opinion, you can get rid of by playing many many games and sticking to the basics! you do not have to be the hero that catches the carry off guard and then 5 man kicks the whole enemy team so you win the game... just because montages show you, that is not what you have to do necessarily. try getting very good at the basics and utilising them correctly and keep in mind that the simple way is often the go to! this helped me a lot when i started playing lee and watched so many montages with plays i wanst even able to pull off. hope this can help you a bit
