To help thouse gzz baba ownage soso out there, here is my topic

sur yes! for max mana boost
whinstans yes, for max mana boost
but would it not be logic to use a spirit, if your in surch of max mana boost?
and wtf, spirit+block is noobborn!
To start, the conclusion

gerke shild is the protector of the es block sorc
gerke shild = unlimted fhr (exept vs smite)
gerke shild = 97% es sorc
gerke shild = your only defend vs ow-psn
gerke shild = +100@resist
gerke shild >+400 total life
(and thats are the stats on a no block sorc, they also get this huge benefits)
gerke shild = 74% block! (24%block, whitout stating dex/20x dex for max block)

why is it so gzzz? why do you need dr-mdr-repl life?
i try explain !
1)+2% es
someone attacks you whit 10k (arround avarge pvp damage)
10.000/6pvp penalty *0.05(es) = 83life lost
83life lost -(18mdr)= 65 life lost
makes you life 83/65= 28% more effective (like 28% more life vs 10k elemental attack or magic attack)
add 15repl life / add mdr-dr overflow(its complicated, but adds another 20-30% bonus to you total dr-mdr(i testet it)
and your life becomes even more effective
(a total +/-40% bonus to life protection, from just a shild)
(i call that +40% sometimes +2% es / 97% es sorc)there is no name for it!
40%*0.05es=2% es
2) the terible things ow+psn attack do to your life (byebye life in +/-10 seconds)
(whit arround 65dr, its posible to completely have no trobles whit ow+psn baba/ama)
(whit 16 dr+18mdr just from the shild, you have no trobles at all vs a gt claw ww attack/mind blast)
no trobles means: you not loose any life vs ow+psn, when your at 1 life = immortal = imune

http://forums.d2jsp.org/topic.php?t=34840334&f=873) mana regeneration

the basic advantage of es, if we not have this, we all would make a vita sorc!
avarage sorc have arround 150mana/sec from lvl1 warmth (fire skiller bild even +/-200mana/sec)
+/-350mana/sec from lvl1 warmth+insight on switch
+/-500mana/sec from max warmth+insight on switch
(google a mana regen calculator to know your exact numbers, couse it depend on sks/total mana)
1k life, allows to regenerate 1k/0.05(es)*0.75telekenisis = 15k mana, before you die (whitout dr-mdr-repl life)
so more dr-mdr-repllife, allows you to regen more mana before you die
what have it for use to regen mana, if your life is gone?
4)resist
the 18mdr, it do more then +70all resist
+30 normal@resist =+100@resist
more details: see link above!
5) fhr
dr+mdr=nn fhr vs normal attack (exept stunning attack like smite)
if you not loose arround 6,3% of your total life ever, fhr becomes useless, like vs a hammer.
15k hammer 6.3%=1984 life needed, or run into fhr motion vs hammer
(15k/6pvp*0.05es/6.3%*100%)
18mdr gerke+10mdr from your armor?=28mdr = 1540life needed, and you wil never ever run into fhr motion

((15k/6pvp*0.05es)-28mdr)/6.3%*100%
the more dr-mdr, the lower life is needed for never needing fhr!
conclusion

gerke shild is the protector of the es block sorc
gerke shild = unlimted fhr (exept vs smite)
gerke shild = 97% es sorc
gerke shild = your only defend vs ow-psn
gerke shild = +100@resist
