Star events are great breaks, no events are bad breaks. You get far more out of a star event than a break. 1-2 days to 3* all maps then the rest of the time is yours to choose what is best.
No events mean no SC which means less farming of affection or fairys than during a break with no event.
Its a terrible idea to go all out on every event and a waste of time unless your spending money on it, in which case its irrevelant whether theres a break or not.
