Having Trials on weekend for Iron banner keep more People playing. I think if you want more players logging in and can't provide a lot of content faste enough , you have to bring out more activities to so weekly. A Good chunk of players play Trials so when you take it away for iron banner ,especially for 2 weeks,you are going to have a drop of players and Making it a boring repetitive 2 weeks . Having the mix of weekly game mode is what draws in players to play. By the looks of it ,the numbers have been significantly dropping. You know this idea is best for you,so what do you keeping ignoring this??
