Late in the 2.1 Elemental Focus Discussion thread, we got into the math behind lightning bolts.

What I've started to do is re-work my old gear calcs, so it's similar in workings to Emmerald's Feral Gear calc, but allows the valuations to change depending on what gear/stats/talents you have.

Got some gem/helm stuff put in, although I'm currently stumped as to how to get an auto-selection of the highest rated gem for each socket type.

Eventually I'm planning on putting in most lvl70/heroic/raid mail gear, and adding in some mitigation/healing stats as well.

So, the reason for this thread is to get some collaboration on this calc, make sure my maths works ok (got to add in penetration soon), as well as getting it to a stage where everyone else can understand it (rather than just me).
