I think in my mind I was thinking of the WoL after BF made it cool to play(noob bash) there, and there was a few competitive kds trying for it. Comparing those days to now the level of competition seems similar. So it seems wrong in my mind to not count a crown back then and count the ones we have now. But I do see your point of there can be only one, just like highlander.
There is no way imo to count crowns and have it be an effective measure of a kd's strength. To me there is only one crown each age, and that is land ofc. Crown counting makes people think that all crowns are created equal and that doesn't sit right with me.
