I would say that people willing to give up the check mark and currency is the personal sacrifice given to shave off as much time as possible for a TEAM win. We could then theoretically go down the path of saying, "Guild X didn't loot everything off of the chest therefore they chose to participate in a win for no loot." Sadly when so many variables due to lag, zoning times, mobs not pathing are out of your control, you do whatever is within your control to have the best time for clearing the tier. It's kind of like last year when "ROI Wiped moving from primal vampire to Close the gate." Every guild had the same opportunity to use the same tactics. Lastly I would ask if hypothetically next year the raid leader for your guild asks you to drop dz for which you bringing up the point about now; will you do what the raid leader is asking or not do it because it would taint any possible victory?
