It massively increases the power of certain heroes, makes other heroes totally obsolete (ie, Boril costume), and makes certain defensive formations vastly better than others.
Choosing different formations should be slightly better than others; with heroes such as Boril or Brynhild in the middle, the new formations are vastly stronger than others, and these heroes become enormously better (as stated before, more like 5 star than 4 star heroes).
This is extremely poorly thought out, and simply makes the game a lot less fun to play.
Nearby radius reduced. Effects that target nearby allies or nearby enemies can hit only the closest targets in the formations, a maximum of 3 targets but less if no targets are nearby. This affects Double and Reverse Double defense formations in Raids and some enemy formations in player versus environment battles. This will be enabled only after all players have updated to the latest version so it takes effect for everyone at the same time
