In Rocket League , your titles (except basic progression titles like “Rookie,” “Pro,” “Veteran”) are tied to Epic Games’ servers. They’re granted based on ranked season rewards, event participation, or special giveaways. A local client cannot force the server to recognize you as an “RLCS World Champion” unless you actually won it.
