I have 2 suggestion for this game. 1. Special protection for players that a not in a group. for example, when a group of players"5 or more should be conceded as a group" fail to destroy a player within a certain period of time, that player should get a special protection. 2. Second suggestion, The top player in the battle list, should have the ability to protect the player at the bottom of the battle list. for example, let the top player known where such player is, go to him, he get a special protection status.
