Viability of Shaman and Rogue Duo

[Barlu]

I'm talking with a friend about starting a duo that we play when we both happen to be online at the same time. For fun I was considering only leveling in the old worlds and not twinking at all since that is when we started back on live. I was thinking with Slows, Heals, and dots the sham could face tank while the rogue goes to town. Would this be a viable duo or would it run out pretty early due to terrible AC and HP on Sham and bad DPS on rogue due to gear?

If you added twinking into the mix how long could this duo go?

On another note since we don't play together often I was considering having a Druid or Wiz as one member of the duo so we could easily get to a spot to exp since most of the time we only have an hour or two and going somewhere only to find it heavily camped sucks. Any cool duos you can think of under the same non twinking old world that would be fun but still effective? Not concerned with min/max as I know the major power duos like ench/cleric and monk/sham but still would like it to be reasonably effective. Also don't want it to include a chanter as that is both our mains.

Lot of restrictions I know but think it would be fun and curious to hear what everyone thinks would be cool. Thanks!
