Any ideas why SE thought it was better to make the new timeworn maps all drop randomly to party members.

The system we always used for older maps was if it was your map, you get all the loot from it. This pushes so you have to actually get maps instead of just join parties and jack all the loot that is randomly given to you.

The only thing that you roll on now is Unhidden Map, Minions, and Thav Silk.
