How season reward levels work
Season rewards in Rocket League are earned by winning, not just by reaching a rank. Each season the reward tied to a rank tier unlocks once you bank the required competitive wins at that tier — hit the rank and the badge alone won't hand the items over, you still have to grind the wins. Win at higher tiers and you can upgrade the reward to that tier's items, so the level you finish on decides what you claim. This service targets exactly that: the competitive wins that advance your reward level, at the tier you're playing. It's a different goal from raw MMR — you're chasing the season's cosmetic items, and the wins only count while they're played at (or above) the tier whose reward you want.
