Yes, those are fair points. It wasn&#x27;t really the actions&#x2F;reducers that were the biggest trouble as much as the seemingly strict design around immutable-only data. I actually think that sometimes enforcing some kind of structure around architecture helps protect it from abuse, and following a more Flux-like design seems to help more than hurt in that respect. However, it was more complicated to explain how this worked rather than Mobx&#x27;s &quot;it works like a spreadsheet&quot; explanation.
