Great post! Its great to see you again. I always get worried when you disappear for periods of time.
Anyway, I guess according to your standards(which are very good) Burgundy and Vladimir-Suzdal could definitely be in though Serbia might require a lot of work. Also, I dont think the Abbasids would fit your standards either.
Maybe you could add Vladimir-Suzdal(or another Russian state), Burgundy, and Bulgaria(as a Byzantine vassal).
I just ask that you dont add Volga-Bulgaria and Ireland. Other than those two factions I like most faction possibilities.
