I'm not sure if there is such a suggestion in this forum and unfortunately don't have much time to check everything here so excuse me if there is one.
I believe it would be nice if we could all have something like a counter somewhere in our screen that will count how many Metins we killed the present day. It's unfair only top 5 players can see their numbers on this. In addition this counter could have something like personal record and could save data from previous days so we can have a complete picture of our progress. If it's possible, it could even keep numbers per type of Metin. If there is a number for every top 5 farmer per week, I'm sure it won't be that hard to let everyone know about their personal numbers.
