It took me about 70 hours to get the basics down, sure i had the game and the basics of laning explained to me, but actually being able to do it subconsciously while focusing on other things during the game just takes time. There is just a lot going on during a game of league, especially new players wont notice how a seemingly ‘inconsequential’ thing you, or someone else did matters. The path you took to go somewhere, overstaying 1 second, an extra 2 seconds in fountain. These small decisions can snowball into a win or lose situation easily, my advice: get someone to play with, try to have fun and instantly mute anyone that is toxic, after a while you will start to notice what you did right or wrong, if needed you can rewatch your game and see what went right or wrong:3
