War win chart was meaningless before because it was an isolated evaluation of kds across the server. Whereas everyone was 'graded' the same for land/nw/honor a kds WW points were decided essentially arbitrarily and independent of the server.
The changes seem to be designed to remedy that so that your standing on other charts lends value to your war wins.
It makes a lot more sense then the previous methods for calculating WW chart points imo.
What's more - it incentivizes war kds to grow and encourages the idea that bigger kds are better. Mirana's arguments against this 'we don't mind growing but we don't want to wast the time' are frivolous, since you automatically grow through warring and if you don't want ant to take the time to fight the best why hold you deserve a crown?
