This is a simple suggestion.
It takes the stats of you on all the top on all the following list :
Battles Won
NPC Battles Won
Skirmishes Won
Total networth
Top 1 on a list will get 10 points, top 2 get 9, top 3 get 8, etc etc. If you are not on the list, you get 0 points.
All the points are automatically added up and divided by 4.
This means if you get top 1 in all the list, you will get 40/4 = 10.
Or top 1 in all but with 1 top 2, 10 + 10 + 10 + 9/4 = 9.75
I think I am writing this more confusing than it should.
