It seems that the Demigod Player Rankings are just a plain mess, still. Look at my rankings for example.

• Since the reset I only played Rook and UB one time.
• Hoever, the page shows that I have 3 games with UB.
• And one game with Regulus, even though I never played him since the last reset (and the last time I actually played him was a few months ago).
• This week I lost some games and thus some experience. I regained my experience from the start of the week after some wins again. However, the experience shown in the Rook rankings always went down.
• In the Demigod Player Rankings you generally see a lot of people having actually 0 minutes of playtime with that Demigod (if you browse through the pages it even looks like more than 50%). So probably a lot of players are in the rankings of one Demigod even though they never played with it.
  

I like the concept of having different kinds of rankings so I hope that this one will also be fixed.
