one of the easiest way to see people performance is the tiem you take in dungeon,with a great group,last dungeon take 12/13min to do,with a good group 20min and when people are "underperforming" it take 25/30min,i can see already "oh for 5 min dont complain"
now to the calculus 12/13 spend more in dungeon,everyday just for expert roulette for 1 month,you already have 360 min(6hour) in the month you spend more in dungeon,now,imagine ALL roulette everyday for 1 month,and you will understand why some people try to rush like crazy in it,because for me,sparing 10/15 hour of playtime doing something else than brainless dungeon, is a lot of comfort.
