I just started playing Mahjong in FFXIV and am currently 6th Kyu with 1546 rating points. What I am trying to figure out is, why is rank important? All of the achievements require rating, not rank. Do advanced ranked matches have a higher rate of rating rewards than novice ones? If outranking your opponents means you stand to gain less rating from a win & lose more rating from a loss, then isn't rank basically a detriment?
