I did that once, but it didn't reall do a whole lot, except catch my brain bug in the firezones once the shield had gone down. And the Plasma bug died from a killshot, so the plasmabug retaliated onto the brain, inflicting more damage.
At the last tournament that I went to, I found that bugs need at least some presence of tunneling assets. Tunneling assets are usually a sure-fire way to get at least something close to the enemy lines. Without them, everything just gets mowed down.
