Just because other features are more important would not necessarily
imply that monotonicity would not be a necessary for any good
It just seems silly that an election method which could cause B to
win if a single ballot was changed which moved A above B would be
considered remotely reasonable.
It is sufficient for me to know that an election method is not
monotonic in order to remove it from any further consideration for
single-seat elections. I am uncertain as to how it might apply to
various PR methods.
