Go back and forth between the dungeons, no real reason to sit out there and wait unless people want afk breaks. But yes the runs get old fast. It's more about your luck of the draw than any real skill.

Other mmo's hide this better with longer lockouts and higher drop rates, which to be honest at this point I'd rather have. You're looking at well over 2000 runs to even get a linkshell of 15 one full set of darklight.
