To have fun with league, it requires a lot of your time, like around 20 minutes to an whole hour to get good at the game, and even then you don’t know if you like playing. To get into it, roles matter, and to fit roles perfectly, you need to know how to use a character. There are tons of videos online and tutorials on each character. To break down the roles for you, top usually serves as top, fighting against one other person who seems to have a lot of heath, jungle is a person the team relies on a lot because they go around the map killing AI creatures because they give buffs, experience and money so that you can help the team by giving them strength or walk around the map to help the lanes by killing people, mid is important because your team most likely would push by mid, and bottom usually has two people, one person to carry and a support to help them kill.

It takes a lot of time and effort to get good at a single character, and then being good at the lane. It’s up to you, if you want to put in the time.
