You can get easier lobbies by telling Warzone servers you're in a location with less skilled players. Some notable examples include Argentina, Hawaii, and Egypt, as they don't have professional Warzone players, and their skill level is low. Ultimately, the best way to find easier lobbies in Warzone is to practice and improve your skills, as this will allow you to perform better in any lobby you join. It may also be helpful to play when there are fewer players online, as this can reduce the pool of opponents you will be matched against.
