its called a speed run... to finish the daily/weekly quickly or to get marks and rep quickly... rng loot is pure luck... whether you go through the whole dungeon or not, getting loot is pure luck. the only garauntee is the marks, or the daily/weekly reward. p.s. speed runs for marks and reps is the quickest way to get legendaries, quit slowing us down because you want to kill every pointless mob...
