The joycon drift on the Nintendo Switch left controller actually adds a fun and challenging element to your games
Ok, so, hear me out. This is actually intended behavior by Nintendo, and only the best players can learn to nail their games and live with this. It adds challenge because you actually have to pay more attention to the game itself and your character. You have to be more alert, and if you some day decide to eventually buy a new pair of joycons you'll be better at all of your games.
For instance, I have a Nintendo Switch and the game
"The Legend of Zelda Breath of the Wild" and while it makes the game itself a bit harder (AKA a pain in the ass) it taught me to be more resilient and try again until
I succeed. So instead of complaining for this behavior like a little bitch, either live with it if you're a broke ass or just buy a new controller. In games like Mario Kart 8
Deluxe this is barely noticeable anyways. The best way to accept it is just realize everyone will eventually experience the drift and move on. It's like a fun, nernetisal challange
