For an elemental shaman, the only time that straight lightning bolt spam will outdo 3lb 1cl is once you hit the T6 realm and have insane amounts of haste.

For pure DPS, what is listed is good, but it doesn't take the classes mechanics into account, like the absolute necesity to crit, and crit no less than once every 4 casts.

It's DPS calculations are fairly well off also.... A quick Dr. Boom test showed I do 2000+ dps on my shaman, I only had about +800 damage and 20% spell crit then. Anything with +hit on it is almost totally worthless for an ele shaman too.... You reach the hit cap with talents and 17 hit from gear.
