We've noticed a few errors in how rank scores are calculated. The time score is now one point per second (previously was one point per minute) and the fighting score is now one point per damage dealt/taken/blocked (previously was 1/1200 of a point). Since this has dramatically increased scores, we also adjusted the points requirements for most ranks. See the ranks help thread for the new requirements. And, for funsies, check out our stats page for information on how rank scores breakdown.
