You're not answering the same question as was asked. You answered with the standard understanding of mismatched expertise weapons, but the question asked was about mismatched item level and lava lash off hand hits.

Which hand should I put my better weapon in? MH for better WF procs or OH for bigger LLs? I assumed it was main-hand but after running an LFR tonight I saw another enha Shaman with Normal "No'Kaled, the Elements of Death" in his off-hand and then the LFR version of the same weapon in his main hand!
TL;DR: Should I have my better (higher dps) weapon in my OH?
It is generally better to have your higher DPS weapon in your MH since you have fewer chances of missing/dodging once you are at your Hit and Exp caps. It is not practical to stack Hit to cap your OH because you are sacrificing too much in regards to other damaging stats/abilities. However, considering that White damage is generally low on our output list, you could experiment with both. I can say that I've seen higher DPS while I was farming for my second Normal NK, by having my first one in my MH.
