No, zeal gives you too much. Speed, uninterruptibility, AR. However, GA is the best armor for this sorc if you can manage to make up mass res in charms. 90 res all for this build is pretty godly, and the increased block will bring your dex req down by about 100 points. Also, 3 frame faster block gives you a much better chance against WW. My rebuild gear setup is as follows:
Dream
Dream
GA (15res/15ias jewel)
Passion PB
IK boots+gloves
Arach
Metalgrid
2x Ravens

CTA/Lidless on switch
90 res all, faster tele, faster attack (65% 10/7 break on zeal I think), 3 frame faster block, max block at lvl 99 with 265 str total (I get 100 from items, so 165 base), 1k more hp (2.5k total probably).
My sorc can clear trav right now, with only minimal potting. The rebuild will be almost as tough as my melee auradin. Given that I can switch in a tgod's at any time and become lightning immune, there's very little she won't kill.
