There is a *lot* less maintenance in the new system. However, realms with fewer knights won't necessarily be poorer than they were. A lord of a rural region with no knights can still easily have a 50% estate that operates at, say, 80% efficiency. That effectively gives you 60-65% of the regions full income, all yours, *and* you don't have to worry at all about production and/or control falling through the floor due to lack of knights. You can also run much higher tax rates than you might have been able to with no knights. With gold and population rebalancing, even half of a rural region's income can be quite generous. I expect that realms like Talerium and BoM may actually see increases in their collectible taxes, and many of their nobles will be freed up from region maintenance to go to war. It should be a good thing.
