DR 50 and Expert were added as tome bonuses to hit your weekly cap without having to grind the same dungeons over and over again (yes, you still grind the same dungeons, but at a much lower frequency after the introduction of DR). DR 60 is just the level 60 version of 50.

Better?
DR Leveling/Trials/Main Scenario also give tomes out, only reason I run them.
