And planetary assaults seem to be for the big guys only now. I'm sending almost 200 cruisers to a planet with 3 mio. people, society 49 - and my surrender chance is 10%.
So, basically, it takes a mid-size empire of over 60 planets more than a week of pooling pretty much all its resources to create one assault force that is on the edge of not being ridiculous.
To me, that means even conquering my inactive neighbour is hopeless. It would take months just to get an invasion fleet large enough that I'd dare attack his home planet.
