yeah that is the way to use it maximally, especially when you have a couple praetorians stacked up. it's just unweildy when you use it that way; weapon swap CD + charge placed into trigger drawn CD is right about the same amount of time for deep freeze to run out (if you're cryo) or for a fire-slowed oppressor to turn fully towards you, tanking the whole blast like a wet sneeze.

absolute favorite is to hop on a gunner's zipline and drop it into a sea of bugs from above :chefs-kiss:
