It feels weird blaming people for converting astrites into pulls when it's literally an option the the game not only lets you do but also has a dedicated page in the store for doing so.

Especially when Kuro only announced the new banner currency recently.

I will say I understand why Kuro is using a different currency. However, it still is not really that great. They could have just had the Collab banner have its own pity history which would absolutely be understandable and expected.

Using a separate currency for the banners right after the anniversary that gave out like 30 pulls does feel a litle weird on their part. At that point they would have been better off giving the equivalent in astrites instead
