Hello, I have only registered to share a very novel idea. And I think quite feasible. And, in addition, we solve a constant problem as it is to let the cups win so that a weaker opponent in the war touches and thus make a minimum effort and get the chest that in comparison with other rewards is much better.
My idea is to make a kind of internal alliance auction. Where the one who has the most cups can access and put a hero in the auction and the other members of the alliance buy it with their gems. With a starting price for example 70 gems and go bidding. You get necessary gems and they want a hero. And they are activated in the assaults to win them and thus be eligible for the auction and not the opposite to win wars.
