I'd actually prefer if the limit was lowered. But have it where the trade in amount was lowered as well. There are alot of people who will never reach the limit due to school, work, sleep, eating, showering, and other activities. This also means alot less stress as you could get the tokens and banner extras in a day or two of non stop play.
The big day for most holidays is just one day. Though it is fair to say it shouldn't be this short. Other activities do happen the whole month to keep things from getting dull. Pet growths still are the main draw as well as daily surprise boxes. I almost wonder what it would be like if Halloween was more like Christmas.
Could this make things more boring? Sure you can say that. Or you could say the fun is increased by removing the tedious farming and simply have those as decoration. Christmas isn't any less fun with the absent of token gathering.
