[Antidote]

This is actually quite simple to do. I modified attack function to resemble what you say (if you want to look more naturally random factor can be added to coord as well)
sample code:

    AUTOIT Programming

Local $numBarbPerWave = Ceiling($atkTroops[$Barb][1] / 2)
		Local $numArchPerWave = Ceiling($atkTroops[$Arch][1] / 2)
 
		Switch $deploySettings
			Case 0 ;Two sides ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
				SetLog("~Attacking in two sides...")
				If _Sleep(1000) Or $RunState = False Then ExitLoop
				;Local $numBarbPerSpot = Ceiling((($atkTroops[$Barb][1] / 2) / 5) / 2)
				;Local $numArchPerSpot = Ceiling((($atkTroops[$Arch][1] / 2) / 5) / 2)
 
 
 
				SetLog("Dropping first wave of Barbarians")
				;Drop first round of Barbarians
				Click(68 + (72 * $Barb), 595) ;Select Troop
				If _Sleep(100) Or $RunState = False Then ExitLoop (2)
 
				$i = 0
				While 1
					For $a = 0 To 4
						If $i = $numBarbPerWave Or Not $RunState Then ExitLoop(2)
						Click($TopLeft[$a][0], $TopLeft[$a][1])
						Sleep(Random(150, 200))
						$i += 1
					Next
					For $a = 0 To 4
						If $i = $numBarbPerWave Or Not $RunState Then ExitLoop(2)
						Click($TopRight[$a][0], $TopRight[$a][1])
						Sleep(Random(150, 200))
						$i += 1
					Next
					For $a = 3 To 0 Step -1
						If $i = $numBarbPerWave Or Not $RunState Then ExitLoop(2)
						Click($TopRight[$a][0], $TopRight[$a][1])
						Sleep(Random(150, 200))
						$i += 1
					Next
					For $a = 4 To 1 Step -1
						If $i = $numBarbPerWave Or Not $RunState Then ExitLoop(2)
						Click($TopLeft[$a][0], $TopLeft[$a][1])
						Sleep(Random(150, 200))
						$i += 1
					Next
