If I recall correctly, at some point Blizzard patched item affixes to make the King prefix easier to find (and amusingly overlooked Champion, which is now rarer than King despite being inferior). With one less high end suffix likely to show up, one would theoretically see other prefixes more often.
I don't remember which version of the game made this change, I'm sure someone else could elaborate if you are curious. I felt it was worth mentioning since you seem to be looking for a King's weapon specifically.
