One thing that has not been mentioned is a particularly nasty side effect of the event limit. If you own significantly more provinces than your dominion spreads to, your luck scale bonus can become almost negligible (bad events from the outer provs override whatever good you'd get). So that puts yet another burden luck- to reap your benefit at all you have to get your dominion everywhere. This is as opposed to order where you are doing fine as long as you get it over your population centers.
