They gave a S rank of our picking, pity is a guarantee 100% weapons don't go away and in anniversary events all S ranks get Featured gacha aka 100%. So you are guaranteed to get your character, plus weapons banner don't go away. So you can focus on the character for the duration of the event and then if you don't want the next upcoming units, pull for weapons. Also you don't need meta teams to do content unless you want to be no1 but like... why?
*weapons are not 100% ,is 80%
