Now, on the US servers, when you visit the overall, world, or guild player list, the players who have been inactive the last 24 hours will be displayed with the background of the row shaded red.
I plan to migrate the changes over to the other servers over the next day or so, and we should also be seeing accurate data in terms of increase or decrease in points, or increase of battles.
Soon, we will be able to display historical data using graphs and other things to enhance the player and guild profile pages.
