  --- BEGIN ISSUE ---
  Визуализировать результаты батлов
  <img width="1113" alt="image" src="https://user-images.githubusercontent.com/19980512/81127819-1f135780-8f48-11ea-83bc-7c56e6e849e4.png">
  
  Было бы круто как-то визуализировать полоску в зависимости от результатов баттла. Чтобы такой раз — и увидел результат, а не подсчитывал, где больше аргументов и плюсов
