i suck at this NW thing. :sad:
The best thing you can do is go into a 20 v 0 map and let people kill you, You'll get rank 1 and 3k personal points.
I always get either rank 1 or 2 but this is my personal best so far. (35 minute Game play) Rank 2 3k Points with 13k personal points, Winning nation third times in the row (Frost Nation)
My highest score in a battle was between 3000-3500k (rank 1) ... usually this doesn't happen often though lol. Last nw got 15k personal score ~ 410 tokens.
