We've implemented the Win/loss ranking on users, guilds, and mirage master. This system only takes wins and losses into account. The Japanese also have RP Ranking which is that value everyone has that starts at 1500. It serves a slightly different purpose, but takes all kinds of things into account, including the relative levels of your opponents. Will be adding that later. For today everyone got a Gran gift equal to the points they earned. In addition, I put up a "Launch Heroes" section to cover games played between launch and last Monday. For the users who made that ranking, I gave them Gran equal to their points in that list or the weekly ranking, which ever was higher. Since the system wasn't set up for it, I had to add in the difference manually (in case someone is wondering why their Gran showed up in two parts.)
Also note that the Mirage advanced and intermediate rankings are mostly just for fun at this point, since there really aren't enough people playing them to make the rankings work out right.
Oh, and yeah we're going to add a little widget on the main page to have the top players and quick links on it, too. Don't worry, the ranking pages won't be be buried forever.
