Hello everyone, I'm curious how is it possible that first 2 guys in division 6 have this much points. This was taken during attack phase of round 2,don't know how much they have know. I had 4197 points at that time and I was missing 26 points from round 1, 17 points from round 2. And only feat achievable for me at that time was Fleet Commander which awards 125 points. That means maximum would be 4365. Am I missing some way to gain points. Thanks
