There are 2 Iron Banner challenges, play games and score points. The first level of both is 3 games and 50 points. On average I get 7 or 8 points per game by playing the objectives, capturing zones, destroying turrets and then capturing that main zone (in fortress). I once saw someone get 15 points but he had captured 9 zones. Sure, it's possible to just run from zone to zone but surely we're not expected to do that? Ideally I should get 17 points by playing objectives , then progress would match games played but on my last character I had to play about 15 more games to finish the point challenge. I seem to remember getting a lot more points in previous IB. Maybe a different mode or has something changed? Please rebalance the point to game ratio.
