I've played through a few full games now, and I've begun wondering about the Centralization slider. Looking at the benefits, it seems that there is no real reason to be decentralized.
Centralizing increases tax and production, decreases research speed, and lowers the war exhaustion maximum. Decentralizing reduces income, increases research speed, and increases the war exhaustion maximum.
Yet, if you look at the income increase/decrease and the tech research increase/decrease, it looks like your tech speed is changed the exact amount your income is changed by (i.e. -1% decrease to production and tax revenue, +1% increase to research speed for decentralizing). This results in no net increase or decrease to tech research speed. On the other hand, because of the income increase, centralized governments can mint more money if they have to than decentralized governments can. This makes it easier to build manufactories, which can dramatically increase research speed.
If you combine this with the war exhaustion benefit of centralizing, it seems that there are no practical benefits of being decentralized. Is this intentional, or is there something I am missing?
