Future Changes? (Pixiv Fanbox)

Heya~ I'm thinking about changing the current plans for both Patreon and Fanbox. I'll try my best to explain it as clear as possible. Currently, we have 4 plans available (5 on Patreon): --Tier 1: 100 Yen Access to basic Fanbox Releases (T1) --Tier 2: 500 Yen Includes Tier 1 1 Week Early Access to basic Fanbox Releases (T2) --Tier 3: 1000 Yen Includes Tier 2 Access to Previews (T3) Access to Polls (T3) --Tier 4: 2000 Yen Includes Tier 3 ---Special place in my heart~ My release schedule would be to start with a preview. Tier 4 and 3 get access to the preview. Then few days later, I would release the project (full or parts) for T2 supporters. One week later, I would change the needed plan to Tier 1. One week after that, I would upload it to pixiv. I want to change this. My idea is to remove Tier 1. Every supporter gets access to all releases and Tier 3/4 gets access to previews. It would look like this: Basic: 500 Yen Access to Fanbox Releases Basic Plus: 1000 Yen Includes Basic Access to Previews Access to Polls Basic Extra: 2000 Yen Includes Basic Plus Special place in my heart~ This would mean every Tier 1 supporters plan will be discontinued. What do you all think about these changes?
