this is how it is, 2 weeks ago they gave us palace, all week people complained about the low silver chest upgrade rate, and one week later they did a patch saying "ok you lazy people, now the silver chest upgrade rate is increased and you'll get a garanteed +1 to both gear after last boss". I still got 2 weapons before that patch, it was totally doable. So i'm guessing for the Yo-kai watch event, if too many people complain about the legendary drop rate and endless fate grinding, they'll patch it next tuesday with a 100% drop rate, like they always do.

If they leave it as it is, i'll just do them a little a the time and only get the weapons i think i'll use one day for glamour, i'll probably skip the ugly ones like the SMN book and PLD shield, i won't get the achievments but what do they give? 10 useless points no titles no items? no big deal.
