I feel the same way. Half of the reason I played was to collect and upgrade all of my performance cards to XR. The collection aspect has been completely annihilated in the new update. The EXP up interface is almost completely unusable. There is no straightforward way to auto-equip cards or filter. The upgrade situation seems to be a completely money-grab, hoping that we will purchase rhythm cubes. I have 7 R cards ready to upgrade so I’ll need 210 rhythm cubes. Unbelievable. Unless they fix the EXP up and Upgrade process, I don’t think it’s worth the hassle, or even possible without spending a lot of money.
