I think the same that testing 9 provinces for 30 turns should be equal to having 270 provinces in a single turn. That would "balance" luck better than anything else...

The single problem with having 50 events a turn would be your lab size actually. Since it's limited to 50 pieces and that random events happen after forging you will lose some of the items on a big map. But some people already lose item on a large map because their construction needs exceed 50 item / turn anyway, so, sooner or later it will have to be made bigger as well.

Some of the good events that actually are not good like the militia have been changed : you get fewer and fewer militia these days, actually most of the time you get national troops instead, so it's not completly useless.

And the population grows events should be far more numerous too... there is about a dozen spell and bad event that reduce population and AFAIK only one that rise it.
