I coupled my low level rogue with ranger. And he usually starts combat firing of his ricochet arrow. Then special arrows if need be. But if not, the rangers skill jump out of danger is a teleport that you can use to jump right behind a mob and backstab.
It almost feels like a superhero move

I usually fire arrow, then move forward with the rest of my AP, so he is a slowly advancing char till I decide he should join in the fray.
