I am a lvl 60 storm 50 fire and 40 balance and I think there should be bosses that you can buy from the crown shop. It couldq b like 1000 crowns or something like that for each boss. They can be any rank you want and you can put them in your house as a battlefield. There will only be one battlefield in your house but you can choose a boss to fight. They can be any rank and school you want and there can be special edition bosses or bosses for sale in the crown shop! :D ( and maybe a meowiarty that looks like this )
