Just my (late) two cents - I find it really strange that WWs are less important while Land and NW crowns are given so much more prominence in this game - a game with the basic premise of an almost-dystopia fixated on warring. Utopia was always a warring game. Land/NW are only accessories to that... but to each his own I suppose.
Its most likely cause the "most warring kd" chart just been introduced while land and nw chart always been around and the competition used to be more fierce. Land is the bestest chart! Its more like its been that warring has been a accessorie to the nw/land chart imo. Cause those two charts have existed.
