When you have an empire of at least 1000 holdings, or even 2000+ holdings, do you bother with King level vassals? I personally don't because I like to keep my vassals weak. This, however, requires constantly dealing with countless dukes and rapidly slows down gameplay after around the 1200s and more so after 1300s when often over half the map belongs to my empire. I have never actually tried giving my vassals Kingdoms, but should I do so after I have 15+ Kingdoms? I mean a rebellious King is much less powerful when compared to a 1000+ holding Empire than a rebillious Duke is to a 1 Kingdom King.
Those of you who have given out Kingdoms to vassals, how does it usually turn out for you?
