I probably should not say this because I really do not know much about the leader board and I have no interest in ever being on this leader board. But is this LEADER board not for the leaders - the best in this game with the most points?

It does not sound strange to me that there are special achievements so you can try to get on top - to become the best. There will be more of these achievements so next time the current leader might miss it and someone else takes over.

To me it looks like you are marathon runners complaining the one in front is running too fast.

But again I should probably not say anything...
