Yes, Zach, but you aren't really walking on unknown territory here. Enhancement shamies are the hardest spec to analyse correctly in the game due to the nature of the damage we produce, so many, many articles have been written analysing the correct and wrong ways to do things.

Your threat *will* go through the roof, the theoretical advantages of linking spell damage crits with melee will never be visible at the dps charts (a better trinket will give more benefits than specing this deep in ele, I'd say), and for a melee class +hit is, if not critical definitely not bad to stack if you can get it, so yes, you'd go as deep as you can to grab that extra 3%, there's simply not enough +hit mail gear.

Basically, dps-wise ele/enh is equivalent to enh/resto, but skewing the damage towards spells. Spells do not benefit from threat reduction, so your aggro *will* go up 10-15% with that build. Now, since shamans are always threat capped, I really cannot see the benefit.

However, I apologise for not having noticed another flaw with your build, that is the lack of weapon mastery. This is unjustifiable and makes this build useless beyond debate. Leaving that talent out is a flat out 10% reduction on dps. I appreciate trying to show something different but this spec is just not viable.
