This has been going on for a while now and it's starting to get to me. The problem is when ever I go to play strikes I end up playing only handful of different strikes. Like I could play the dust palace then a strike or two later it shows up again and thus happens on a regular basis. This leads me to believe that they are not randomly selected. It seems it weights a couple strikes alot heavier than the others. I'm not sure I'd I'm just unlucky but it's frustrating playing for multiple hours and not getting the strike I want so I can get my loot.
