lol games don't come with a mouse or keyboard.
The reason is that, as an esports game, lol tournaments are usually held in professional esports venues.
In these venues, players need to bring their own preferred mouse and keyboard to ensure that they can use the equipment they are familiar with and suitable for their operation during the game. In addition, each player's mouse and keyboard needs are different, some players may prefer a mechanical keyboard, while others may prefer a thin thin film keyboard. As a result, providing a uniform mouse and keyboard may not meet the needs of all players.
For esports games, the mouse and keyboard are important tools between the player and the game.
Some professional players will choose their own equipment according to their own needs and game characteristics, in order to improve the game's operating experience and competitive level.
Therefore, it is very common practice for players to bring their own mouse and keyboard for competition.
I brought my own, because my own keyboard and mouse are more convenient
