Thank you so much for the feedback and for checking out the dev log! I do hope to have this stuff addressed soon -- a lot of people agree with you. I agree too.
We're working on having cards to choose from 2-3 random buffs instead of the wheel for stages, and I'd like a rule set where there will always been one active play vs one passive play to choose from. We'll keep the wheel because wheels are fun, but we'll probably attach that flow to achievements, prestige, or both. Just a fun boost instead of critical growth.
I think the new currency splits will help, with global and stage-based being separate, so hopefully there will always feel like there's long-term progress.
I'm also working on rebalancing the stage requirements, and prestige is WAY cheaper now (250,000 and I'll see how that feels.) There will be another big update at some point, but it might take a while to get everything rebuilt.
