I struggled to find good guides for this, but this is by far the best one

Dont make the mistake of using ES on a blizz sorc. Its the worst way to build blizz for pvp (none of the es builds use oak either, which is the strongest defensive skill for pvp)
So you would sacrifice litteral all ur survivability for doing 12k damage with less negative cold res modifer instead of 10k damage.
it does not matter if ur sorc has 2k or 3k life, its zero dr etc...
Ur limiting urself to be a decent vs elemental damage, and sucks vs physical and magic damage.
And not to mentioning, what do you do when you duel 3-4 different character types?
Is reduce damage done to mana with 1,25 or smt if 20tk.
A auto fast replenish mana pool of 4-5k will last way longer than 3-4k life.
Not to mention you can have both mana + resits/DR%.
My d2lod sorc had:
45% DR, 10k blizz damage, 105fcr, 86fhr, high mana and life repl, 75@ with stacks and max block with 3,4k mana, 95 es and -275 enemy res.
By swapping gloves i had 4k mana and 30-40% block.
A blizz with more regular items should focus on nb, reach 4,5k-5k mana, 10-11k damage, 100fcr etc...
Ur life will easy be 1,3-1,6k anyway.
Amplify damage will not affect ur DR%.
Lower res, conv and facets etc will not affect ur mana.
So all theese modifiers people may focus on has little effect on ur mana, and thanks to es little affect on ur life as well, espeisally if u build it well...
So vita vs es we are talking about a total damage loss of 2k blizz damage. 12k vs 10k.
