They need to do something about the 4 stars

Title. They need to make all 4 stars unit tradable on rotation. Not just some old ass 4 stars that keep showing up. I swear sometimes it’s even harder to get the 4 star unit than 5 star…

True story. I have a C5 chev. I need her C6 so I decided to pull on this banner. Wouldn’t hurt if I got C1 Arlecchino and the new Lan Yan in the process. I spent a total of 150 pulls now. Got 1 Qiqi, 0 Lan Yan, 0 Chev. All those fucking Rosaria… I’m so fucking mad it’s not even funny. I can’t pull any more because I don’t want to waste that pity so I’m gonna be stuck with my C5 Chev for months now. It was the same on her last banner too.
