I've found a technique which I assume to be some kind of bug, where you can actually shoot the guardian through dome if you dome the tip of the guardians head. It's pretty precise trick though - I only tend to get it 1/4 tries - I've not done it in a match but I've included a video of me doing it in the practice range.
