So, this is a question that Wowhead's rep guide never really definitively answered me, and I haven't found a clear yes or no answer to: can Armies of Legionfall rep be brute-force grinded, or do you pretty much have to wait every day for world quests to materialize? Can't I just go out and kill demons by the thousands and in some way grind rep via either turn-ins or dozens of dungeon runs?
Also, is there any way to get rep from the Cathedral of Eternal Night?
