Imho, looking at the other rank is unhealthy habit So close the statistics page at all. Or alternatevly: statistics could show the first five players with highest rank, but without information about research points, resources, etc.
Statistics should be shown for everyone, or not shown at all.
Anyway, I agree that these statistics provide FAR too much information to potential enemies... why not just list the ranking of everyone, without breakdowns into research, etc...???
Make people gather intelligence for themselves about their enemies?
