Is there maybe something wrong with the way these teams are decided? The last time this happened (see linked topic) the duplicates were ALSO on teams #2 and #4. And if this was intentional (i.e. no duplicate prevention) then we might expect this to happen a LOT more often than simply twice ever … we’d be reporting it almost every week.
Also, please consider the request that after completing a tier of 5 battles, the Class Trial should reroll which teams are available to fight.
