Yeah i was adding onto the thought that the decline of empires would be preferable as generic than tag specific events, and so ottomans also have some events they'll only have once an empire so the game has existing mechanics we can make available for all.@The Norman Yoke I think the idea expressed by @MachopPower69 (and the one I expressed) was that those unique events for the Ottomans would be replaced by that more general mechanic about the decline of empires, albeit they could keep the localisation for the Ottomans if, by chance, the particular of the situation match with the one said in the "decline of the Ottomans" (by the way, it's silly to get those events when you are doing fine elsewhere and dominate the whole world).
That said, I agree with you when you say that the AI should know how to react to those, especially if they were to be extended to all countries.
Yes I would prefer it if various tag pre scripted rebels/unrest events would be looked at more and possibly fleshed out.
Eg: The sikhs only rebel if you choose to execute their guru as the mughals. The reapers war with the Catalans only fire if France is a rival and you've recently been at war.
