Well, rebels are tedious as hell, I can attest to that. In my Extended Timeline game as Japan I started westernizing when my empire stretched from Honshu to Moscow and Libya and Ethiopia (2600 points needed). I've culture converted pretty much everything that's outside my culture group. ~98% religious unity (Arian, and japanese provinces keep flipping to Shinto -_-). Enter -30 legitimacy events dumping my legitimacy to 0. 3-6 new rebel stacks every month. At this size I can only really use autonomous rebel suppression in Japan, as in the rest it would mean an army would start marching from Georgia to Korea and back even though the rebels are being taken care of by an army closer by. There's no difficulty defeating them, but spending NINETY in-game years pausing every month to give orders to move between provinces... not even close to anyone's idea of fun.
Oh and yeah don't get me started on "We need a shakeup!" while I'm still coring conquests from my previous war, or Incident at Honnoji...
