Marks shouldn't even be able to be reset honestly. If you didn't get there in time, tough shit, plenty of other Bs and As. There comes a point where you can't wait for everyone because contrary to what people want to believe, you can't get credit on a mob that won't even load on your screen due to the ridiculous amount of people showing up. The Horde imposing it's rules on the people that aren't part of the group is just wrong, plain and simple.
