Mines and alliance ranking

I think maybe the alliances would be more active if the alliance prestige was reset each first day of the months. The members would keep their contribution points. Only the alliance points would be reset. The winning alliance could get a price each month like crop or money or the member of the alliance could get 10 coins each. In that way it would be more war. I've only been thinking of it for ten minutes so other ideas or adjustments of my idea are welcome.

it would iradicate the level system teams have already spent loads attaining so not a good idea.

I agree it would not feel good to get reset at the time, but it's nearly impossible for any new alliances to gain enough prestige to be in the top. And the longer you play the more static is the ranking and what is fun with the mines when there is nothing to gain? All you get is the medal behind your name, but after a while everyone will have it. I think it would me more interesting with the mines if there could be a change in the long term to keep the players active.
