The droprate and exp up is pretty good for farming great story cards and raising friends, so why keeping that just for main story?
Sometimes it's pretty tiring having to farm DS content or the Elemental Ex, be it for time consuming or too much things to do, to get nothing at the end in your farming session or taking a lot to get a single mlb card. So my idea is when this events are live, all content have it, obviously with some limitations like Total Base lvl 100 in DS stages and so on.
This will probably motivate people to farm more and make new strategies for it.
