Good day,
As of right now, the DR threshold is set too high. A group of good players has absolutely no difficulty clearing 4 paths in the arbitrary two-hour threshold set by god knows who. Even with “slow” dungeons such as HotW2/3 in dungeon rotation, you are more than likely to receive DR’d tokens.
This is punishing good players for being good. It’s a bug.
Have dungeon DR kick in at 5th path in an hour or remove it altogether.
That is all.
