With the new update we introduced Spectator Mode. The new mode replaced the “Attack” button that was visible when a player clicked on a fleet that was attacking a base. This method was being used to ambush, or “ninja”, a fleet immediately after it attacked a base.
This method of hovering over the attack button while a player is attacking a base has been removed because it requires zero skill. A player that has finished attacking a base has to wait for the world map to load and close out the battle report screen, while a player attempting to “ninja” only had to click once to attack. There was no defense against it and required no skill to accomplish.
Players are still welcome to attempt to ambush a player after a base attack, but now the player that was attacking the base will have a fighting chance to escape. In fact we even encourage players to try to ambush other players to see how wicked fast you can be and show off your skillz. :cool:
