Maybe we could have those chests back. The chance to get one would be incredibly small, but you get a bonus to that chance every 20 minutes you play. After 2 hours of playing the same character, your chance to get a chest is around 2% per kill (just throwing out numbers, this would need to be tested though).
There would be individual rolls for everyone. So let's say player A is in a group with player B. A has played for 5 minutes and B for 2 hours. Player A has a .00000001% chance to get a Emblem Chest, player B has a 2% chance. They kill an enemy. Player A didnt get a chest, but player B received one that contained 30 medallions (just throwing out numbers again, would need to test).
I like brainstorming btw
