Wow, there are some really great ideas floating around in this thread, I actually hope the developers think of incorporating some of this stuff.
First off, I am completely with those of you complaining about how rebels are handled, I have had two Ottoman runs ruined by the Peasants War event firing, a 96 Stack popping up in constantinople, combined with Wack-A-Mole in every 2nd province I own. More generally I am sick and tired of crushing a rebellion in a province only to have the same province rebel moments later.
So some of the ideas I like are:
1. Scaled Rebels - Historically Peasants revolts got absolutely butchered. A professional battle hardened Stack just coming back from a successful campaign against a real army should cut a swath through mass numbers of Peasants. Therefore I really love the idea of 'Peasants' revolts involving an easy enough to combat horde, but with penalties then enforced to overall national production/tax/mapower regeneration etc based on the upheaval of the situation as peasants cause upheaval in the countryside.
I then like the idea of Pretender rebels, i.e. the real hardcore type revolts being much more problematic as perhaps generals, army units side with the pretender King or something like that.
2. Funding evolts - I like the idea of revolts becoming harder/more severe being tied directly to other countries 'funding rebels'. I think this would add to the whole espionage side of things which I have so far ignored in over 200hrs of playtime. I think it would a be a useful and interesting mechanic if one power could directly undermine another by using the support revbels feature to cause otherwise minor stacks to start getting boosts in moral, pips and even outfitting (cannons/horses)
3. Peasant War Event Chain - I'd like a complete overhaul of this event. Historically several countries in this time period suffered large scale peasant uprisings, particularly Germany, but others like Britain and I think maybe Russia. I hate the arberary 'hit low mapower' and whatever the hell the other triggers are nature of such a potentially interesting event. Rather than just a single pop up and then whack-a-mole for years, I wish it was a fully fleshed out series of events that you could make multiple decisions to influence the direction of the revolts, maybe even culminating in a change of governemnt? (an underused feature in my opinion).
Frankly this event is terrible and not fun. I know having your country decend into chaos isn't meant to be 'fun' per se, but the way it is currently handled is absolutely ridiculous and has reached a point where, when it happens I pretty much just restart a new game, because why bother whiping out stack, after stack, after stack, its not fun, but more importantly its NOT INVOLVING. I am not sucked into a narrative that my country is experiencing a crisis to overcome, its more of, lets set an artificial barriar to player expansion in the most OP and unfair way possible. Plus, based on reading of some threads, if your someone who botheres to look at game files and learn all the hidden mechanics its easy to avoid. So essentially the people most equipped knowledge wise to deal with it can avoid it, and those of us who play for fun are stuck with this crap.
In conclusion, social upheaval events have a potential to spice up the internal empire management aspect of the game that is solely lacking at present. As has been noted, the game is too focused on outward expansion so that essentially the game is one big war sim and is about painting the map with peactime functioning as a rest period between conflicts and nothing more. Internal social upheaval, with a full scale overhaul and even paid DLC (yep I'd pay) could add interesting internal management decsions to the game that would increase its fun and longevity.
So paradox, please do something, anything, about the way rebels function in game, cuz it currently sucks .
