Some people just do dungeon-fishing. Every atma book require you to finish 3 dungeons (kill last boss etc.) with your relic weapon.
So instead of queuing into low-level dungeon on lvl 50 char, they go into DR trying to kill two birds with one stone. Wrong dungeon? Quit, repeat.
Even with 30 min penalty it's ok, you still can kill mobs / wait for book FATEs while waiting.
