A Ranking only for rats, a Ranking only for snakes, a Ranking only for pigs and a Ranking only for wolves and of Course the normal raze Ranking with all Razed villages.
Killing a rat is very very easy but a wolf is difficulty...that should not be put into a list together.
P.S. And a Ranking of Achievements would be also good, but this is not so important ^^
