Other major cities can actually recruit troops, if they secede.
Another good incentive to secede.
If your realm has several major cities that you'd like to see recruits recruited in, then plot with their dukes to form another realm.
Or if that fails, join a realm that does have the conditions you like.
(atleast i would)
I'd rather see those cities fly their own flag then to fly the flag of some already massive realm being nearly useless compared to their independent state.
