The leaderboard now has expandable rows: clicking any row shows when a player logs in, how many hours they played on which days, and how those hours split between the two servers.
What you see right in the row
Even before expanding, the table row itself shows: the day as a single graph, the number of days the player was seen, and a faction icon instead of a name.
What the expanded view shows
After expanding a row, you additionally see: the peak activity hours, the hours broken down by day, the first and second server shown separately, and which faction the player plays for, broken down by match.
Sorting
The table can be sorted by hours, kills, K/D, CASH and number of days. Under the column being sorted by, a scale appears showing how far the top result is ahead of the rest.
An hour on the server is no longer shown as a weekly total, but as the time a person logs in. Two players with the same twenty hours can turn out to be different people: one is a morning player who keeps an empty server going, the other is an evening player who shows up to a full lobby.
