Another point to note, is maybe many players do not prefer to be in larger realms.
On Dwi, BT, and EC more than half the realms are under 15 nobles.
Myself, i prefer to play in smaller realms.
There is more likelyhood of moving up through the ranks.
Your input can carry more weight within a smaller realm.
There are less people to convince when you want to direct your nobles towards a specific goal.
Certainly, a realm can be too small to be effective, but I don't think setting an arbitrary number of "10" is truly the way to go.
We always hear about the advantages of a larger realm, but there are also advantages to a smaller realm as well.
Personally, I think that the real problem is that there is too much "map" for the current number of players.
