To lower your rating in War Robots, you need to lose league points. The first step is to participate in battles and let your robot be destroyed. This will result in a loss of league points, helping you drop in leagues.
Another way to lower your rating is by playing with underpowered robots and weapons. Using lower-level robots and weapons makes it harder to win battles, which leads to a decrease in your rating.
Focus on capturing beacons and dealing damage during battles. By actively engaging in battles and trying to capture beacons, you will lose more league points when your team loses, helping you drop in leagues.
Leave battles early if you lose all your robots quickly. This will maximize the league point loss and help you drop in leagues faster.
Avoid winning battles or dealing significant damage. By minimizing your impact on the game, you will gain fewer league points when you win, making it easier to drop in leagues.
