Multiple Spam marches to a tower as reinforcements locks the attacker in tower for about 4 seconds with no hero returns and forces the hero to face all the reinforcements that arrive in that 4 seconds.  Please fix this.  The marches force lag on the tower and forces the attacker hero to stay and hit more than what was in there before the lag.

This allows cheating.  Players can send tons of marches at tower even if there is not room for reinforcements.  This is causing attackers to get stuck.
