Two things:
1. The continent separation makes major problems, because people, with good reason, have their characters all follow a religion from their first realm...That doesn't show up anywhere else.
2. Until and unless religions gain the ability to passively gain resources, nothing will change.
If you don't believe me, look at the new tax system. I don't know about all realms, but I haven't heard of any major fights over the Crown suddenly leveling taxes on the Dukes except in connection with ongoing disputes. Why? Because the game now allows it, and it happens passively. Three months ago you couldn't have pried that gold out of the Dukes with a crowbar, because 1. the game didn't say the Crown could, and 2. it took weekly effort.
Weekly effort doesn't happen in this game if there is any way to avoid it, it's just that simple.
