Solo Shaman (mid 40's) Mana Efficiency?

[Buffet_Shammy]

Hey Folks,

Looking for some advice on the best rotation you are using to solo mid 40's. I've been leveling up to this point and hit or missing with the pet yanking 50% or more dmg.

Should I be focusing more on root rotting and keeping the 50% exp?

Issue is if I have pet tank the mobs need a slow... otherwise pet explodes.

I appreciate the feedback!
