Well, my suggestion as say in the title is that you make a new server where everyone starts at 0 I think it would be nice and could make this game exciting again Aswell would be nice that the people couldnt buy pokemons there I think tradings made lose the magic of pokemon. Im not suggesting that you close your actual server I mean that you make a new server keeping the other online. I think it would make its game more exciting.
PS: sorry about my english
