This website: https://www.warzone.com/wiki/Statistics_Window implies there are all kinds of stats including a “relations” tab that would show armies killed between players etc. but the stats I have access to or can find after my games seem very limited. Where is this relations tab/info?

The Flash version used to have a bunch of stats. If you switch to Flash (and if Flash still works on your device/browser), you should be able to see those fancy stats.

I don't know if they were ever re-implemented in the Unity version. Seems like not.

You can see them during the game btw. Hotkey 'y' I think, or you can use the menu in-game.

The wiki is terribly outdated
