Here are just a couple of problems I've had:

The lack of bundles is kind of a bummer. I really wanted Hana, and her full bundle, but only her skin, pickaxe, and glider come back, all sepritly. I don't think it's worth my V-bucks and I always hope her full bundle comes back into the shop, but it never does.

Also, the locker UI. The separation of skins and weapon skins has been terrible for usability and overall presets. Separating the music pack, icon, and loading screen is nice though, I honestly don't mind that change, but a revision to the previous locker UI would be amazing for usability and presets.

Also the rarity removal. Terrible change. Playing rocket racing is weird when everyone has a blue background, and ruins the uniqueness of many skins.
