Attacking an opponent in that map means you drain your own army, drain your own gold and other resources, means you you will lose if the other 2 teams are competent.
The way Kiara played that map would have been fine and ideal if it was a larger map, procedurally generated and randomised so the other players wouldn't know her location.
Just move on, Kiara made dumbass decisions in terms of strategy vs map and it cost her the game.
