With so many categories encompassing all aspects of the game I am surprised there are no war Mode achievements and no war mode categories on the leaderboard.
This is an Idea we've already taken on-board: http://forums.kanoapps.com/threads/guild-wars-stat-tracking.13310/ It's been in the queue for months now, despite my pestering to get it moved forward.
I agree 100% and I am not even a War Mode player, but when my friend @Justin Cartier recently informed me of the Points he had accumulated during last weeks Season I asked if he may have been the "Top-Scorer" overall for that Season, and he informed me there was no way tell (besides asking other War Mode players, but because they are essentially your "enemies", that will likely never work! I thought for certain there HAD to be a way to see if he was last Seasons number one scorer, so I began searching EVERYWHERE for something that would give me information on War Mode "stats", but came up empty after nearly an hour of looking. Again, I am currently not even a War Mode player, but still can't believe that there were absolutely no Rewards (as we both believe with certainty that he had the highest score last Season) or even Achievements for his feat. I guess we should move to the Thread @mi7ch mentioned above, as this is yet another much needed change!
