except it will never grind to a halt, we're just looking for a week break or so. fyi, we can because this is a star rush. but what about the past 2? having heir to strategist and monk training back-to-back gives you almost no chance to get some aff/levels. In order to beef up your unit choice there'll always be stuff to do during the breaks.
Also, you're forgetting about newbies who join late. the more back-to-back events, the more events newbies will lose out in. you can't only think about the long-term players, a balance is needed. And don't forget, nutaku wants people to spend SC, but without getting your bunch of previous summons ready, would you be more or less inclined to summon more?
