I very much agree that a ranking which takes recency into account would be a very healthy fit for a game like FFR- seasons in particular may or may not be the best way to achieve this, but i think its a pretty good idea. I think an additional touch could be a somewhat-regularly changing pool of charts available to be played for this "seasonal" ranking. This would serve to discourage just grinding the same charts you would otherwise grind and help newer charts get more exposure.
