Hello sir, I'm a rank legendary 4 tenno, the capacity of the riven mod has not been expanded for nearly 3 years since the opening of the legendary rank before 2022, and ]now i have saved nearly 200 rivens that have not been opened, every time I open a purple card, I can only ask a good friend to help me scratch out the task to open the riven, I hope that the capacity of the riven mod can be expanded to a certain extent in the future update, thank you!
