There is an overwhelming amount of information for a new player to learn, and League of Legends should be easing the player to more concepts about the game over time. Instead they put no effort into helping a player understand the game. The “tutorials” in the game are an absolute joke. They set up players for failure. Tutorials not only teach the game to new players but serve as an introduction to the game itself. Players will base their opinions about the game based on the tutorials and the first few games they have online. The tutorials are the driving force on how people perceive and experience those first games they have.
When these core concepts are not taught in the tutorial it is a problem. Because that means the player is forced to learn those concepts elsewhere. Whether that be in-game or a guide online. The player’s experience will not be tailored to be understandable, forgivable in mistakes, or correct information. The game runs the risk of losing that player.

----------------Tutorial Alternatives---------------------------------------------------

Tutorials aren’t the only way to teach new players. A simple effective way to help players would be to add training drills. This would give new players a playground to get used to the basics of League of Legends. While avoiding all the confusing events in a live game. It would give structure for a player and ideally show the player’s progress on how much they’ve grown over time. farming, jungle clearing, skill shot dodging, and kiting, would be great additions. These are simple events that happen in a game that Riot can easily put into mini-games that would be forever relevant in the game of League of Legends.
“Practice Tool” should be the place to help players but it fails in that aspect. You are still limited to the champions you own. This is a huge detriment because experimenting and playing with a champ is the best way to learn a champion. “Practice Too”l doesn’t provide any structure or guidance for a player. So the player needs to know what they want to achieve when using “Practice Tool” but a new player wouldn’t know how to teach themselves.
The lack of real players in “Practice Tool” ruins a lot of learning value. You can’t practice with allies or invite your friends. You are only allowed to add one enemy bot. If you want to experiment with different champion interactions, practice laning phase, or learn to dodge skill shots you will have to make due with an AI which doesn’t simulate a real game at all. The learning experience for a player shouldn’t be a lonely one. When you are forced to be in an online game with a friend they can’t solely focus on you. Their attention is divided. There should be an environment where people can learn more about the game together.

------The Aftermath------------------------------------------------

This is why so many new players quit. There’s just too much too soon. An overwhelming amount of information that the player has to learn by themselves. And why would someone go through so much trouble just to play a game they don’t care about. They haven’t built a connection to the game yet, so they will just move on from League.
The biggest offender of lack of info are all the different champions. With over 160 champions Riot still gives no practical way to learn them all. They give the briefest of descriptions for what champions do in their own client. However, such little information is given that it is basically useless. In order to actually learn what a champion does you have to be in-game where you have more in-depth information and can see the abilities in use. However, you can only play champions you own. So the only way for a new player to learn more about the game is to go online and watch player made tutorials and guides.

----------Conclusion------------

So what’s it matter if players don’t know everything? I mean they are having fun right? Well, the problem still exists for some that the complexities of the game will be too much. Too punishing for the player to ignore, too difficult for the player to overcome while still having fun. Riot has given up on these people. Limiting the potential players that would have joined otherwise.
The only conclusion I’ve come up with is that Riot wants to spend as little time as possible teaching the player, so that they only play online matches. To help their player count numbers. It doesn’t matter how much information a League player lacks. As long as they can move around and occasionally throw out abilities, you can be thrown into an online match. Riot would ideally put you up against other people of roughly equal skill. Then any knowledge or ability you lack won't be a problem. You’ll experience the highs and lows that the game has to offer just as much as any other player.
