honestly ime this is a big mistake when engaging with muta/roach. it takes way too long for the mutalisks to focus the colossus and the colossus will move back resetting the muta attack + muta acceleration is way too slow.
the colossus also have such a wide surface area that they soak up much of the splash damage. you are doing far less DPS this way to the ball as a whole. despite the fact that
this is why you need to base trade unless you have overwhelming muta numbers.
