I'm one of those people that can play one or two days one week and then five days the next week. I can manage three daily roulette bonuses on my short weekends if I pay attention to the reset times. Add on the fact that one of days off on short weekends is maintenance night during the hours that I am awake which cuts my possible play time in half and it becomes very difficult to cap tomes and get anything else done in the real world.
With a cumulative cap, I could do my dailies on my short weekends and then finish the caps on my long weekends making it feel like less of a chore. I am greatly in favor of this type of system.
