Right now I'm dual boxing with a 26 warr/shaman. I'm going through the levels so fast, I'm not sure that I'm using the right spells/abilities!

For the shaman, I drop a fire totem at the start of fight. Then I just use Lightning Bolt for the rest of the time.

Should I be using other abilities? I want max DPS on the mob, and I only want to use the best 2-3 spells. Someone please give me some analysis on this.
