Well, it might be a complete waste, but there's the possibility for making 1 (or 2 or all 4) of the hunters an engineer. More hunters= more chances for jumper cables to proc. (also works well with rogues, for vanish)

And another point, Vyndree, I remember seeing the video of (assuming it's you, because it's on your website/post) with 5 hunters. How do you get your pets to split? Marcos to attack {star} (or something like that), or just the fact that the video is speed up so much you focus on the targets for the different hunters then hit 'go?'
