I support the idea of having revolts when unrest is high. In fact I'd even prefer to have a small chance (say 15%) of a (small) revolt occuring when unrest goes above say 50, then the probabilty should rise up to a serious chance (65%) when Unrest reaches 100, with bigger revolts if it's above that... A 500 Unrest province should have all its able population take arms against such an awful ruler
This would give player a good reason to keep unrest low (other than maximizing gold income)
