Good point, a ticket is "almost" (using term very loosly as I don't know the rates) the same a 5 dragon stones for a single summon. So if you look at it that way, you are given 10 stones but forced to use them on single summons for this banner.

So 12 stones a day wooooh, just you can't save 10 of them.
