The whole point of the event was that you didn't have to do all of it, and that you actually had to put in time if you wanted to get everything done. I'm pretty sure that the guy from the Yo-kai company specifically wanted it to be "long" and not an event you finish completely in an hour and then it gets to stand around like a ghost town for 80% of the time it's active. Unfortunately, the only way to do an event that's available to all players without being a copy & paste of the Lightning event will require FATEs and RNG. Though I will concede that doing something similar to the lightning event where parts of the event unravel every week or so is much more gratifying than an Atma farm, and will not test the sanity of players who feel compelled to fully complete it. All in all, it probably could have been handled better, but I'm sure that more time was spent in creating the weapon designs and the minions than anything else.
