Meh, though I can see a minor justification for Divine Mandate given the whole thing of the Emperor being God's regent, but it really seems like more of a China thing. The whole Divine Mandate, from my knowledge, wasn't really pushed as a way to legitimize the rule of an emperor or legitimize an emperor's general actions. Really, the only important role it really served was an excuse for the emperor to interfere with the church and replace those against him with loyalists. Basically, though it was there, it was nowhere near as big of a role and certainly couldn't call for a "Divine Mandate" government the same way representing a space Imperial China would. In conclusion, I will not be switching as I feel Divine Mandate has weak justification and, if Despotic Empire continues to fail, I will be switching to Martial Republic as that sufficiently matches the Roman Republic, although it is difficult for me to tell whether the Roman Republic historically was more of a martial republic or oligarchic republic.
