I don't know about Jerks' crowns being worthless (as in for some reason the details of those crowns escape me); but I agree fully that Emeriti's crowns are largely garbage. Pretty much if you were snatch up any kingdom from "back in the day" who existed at the upper end of mediocre in skill and activity (ranked by past standards not today's), they could all easily crown over and over and over in today's uto.
