You have to look at it from the other point of view as well. If all those people trying to do the dungeons for relic weren't around, your 30 minute wait to be in the dungeon would stretch out to be 1.5 hours +. I rather do a speed run of a dungeon and get the completion bonus than wait 1.5+ hours for a exp run. Does everyone not remember the que times before they gave incentive to return to old dungeons? DPS on Aether waited upwards of two hours for certain dungeons.
