World of Warcraft; Shaman Question?

Now, I'm a healer, often said as having some of the most beast heals people have ever seen, I have loads of Intellect and Stamina and Spirit as well, but when I switch to dps specc, I don't think my damage is quite up to par, so what I'm asking is, what stats should an elemental shaman have? I only do between 1-3k damage a hit, is that about right? I saw an 80 shaman who had only stamina and agility, but that can be right, ehh?
