I want to suggest better signals for atacking

id like to suggest that game needs signals of swords etc, to let other players see where we are going to battle.
Because in the middle of wars, nobody listens, just symbols can make team work together.
so i suggest to be able to give a signal of a sword, to the place you want your allies fight with you, and that sword keeps there on the minimap for 20 secs not 3 seconds, so alies can see them.

Also a signal of a shield where you want them to send army for defense. Because i repeat nobody listens, just signals unifies armies. The art of war of tsun zu says this.
