As i think quite alot of people feel having 1 week of sieges and then 1 week off can be difficult and overwhelming for revolts etc. Not only does it remove quite alot of fun but also makes white bannering basically useless. My suggestion would be to have 2 weeks of sieges 1 week off this means that if you were to white banner you can siege again the week after. Not only that but sieges can be more spread out. While still having time for other things like grinding and regions in the week off while still making sieges more fun and more enjoyable due to not being overwhelmed by like 5 sieges in 1 week.
Thanks for reading.
