Only issue I have with this game is when 2 people join and use this advantage to win every game. They obviously don't attack each other and this is their way of ranking up. I've never played a master or grandmaster that doesn't have a 2nd device or player, in game to assist them. In my eyes thats cheating. Can't rank up normal? Yeah I thought not. IMO ranks over expert are false and there should be a firewall or game change when players do this.
