When Season One begins, all pre-season rankings will be reset to default for a clean slate. Throughout the season, ratings will be available via web-based leaderboards. Although there is no definite date set for the end of this first season right now, BioWare is looking at a six-month run. Then near the end of the season, exclusive rewards for various tiers of ratings will be announced. And once the season ends, there will be a break before Season Two gets rolling.
