I dont play a shaman, or have one; but a friend of mine who is new to the game does. She asked me to design a build for her, because I had always given her advice on leveling and things like that.
When she got to around level 46, she re-speced, with my specifications. Since I dont know a whole lot about what shamans need to fight, I was wondering on if the build I chose was any good. She mentioned she wanted to be Elemental, but had originally been a hybrid, so I designed a build that made the most of Elemental and Restoration, with mostly the latter by the time she reached 70.
I decided to go for something that would maximize the damage, with the least mana cost to compensate for any insufficient skill or gear. The last two points are basically a dump, so I was unsure where exactly they should go, and advised her to make a decision based on needs and play style.
