Funny how i just teamed up with a commando today as a commando myself for a heroic 4 quest.
We were both gunnery specced with 2 Elaras healing, and we were both underleved compared to the mobs on the quest. And it was a breeze, we didnt even come close to dying not even once.
2 60 second stun, focused burst dps and sustained healing. Yeah its pretty easy.
