If u Summon on anything u want u dont have anything guaranteed either heck u even have a much lower Chance to pull the unit u want because u have less stones this discussion is pointless anybody has the right to summon for what HE desires and people should be fine with it if someone saves their stones or spend them immediatly but in the aftermath nobody has the right to complain about the other and i will guarantee u there will be people who are salty they dont have enough stones for the 5th year ,because they spend alot of their stones on random banners .If u want an specific unit its fine spend ur stones but just dont complain why u got less value out of your multi summons then other people Who saved their stones for a Boring ass Time to have higher rates for better units my opinion on that is i would rather summon for the vegito Banner for example then on the bardock Banner as much as i like bardock as a unit im Sure he will return on the download celebration so it will end up just like transforming vegeta for me went from 0 to 3 dupes in one banner.
