Well, I actually tries to play the standard game a week earlier
called Ultra Weapon Girls.

from what I noticed, there's no change in daily mission reward/pricing compare to that.

but the gacha rate is never shown in both game, so I didnt know that there will be a change or not.

(they only show the rate of character in case you get a unit., but not % that you will get a unit, usually you will only get pieces or random item.
