In stead of thinking about a cooldown/cast, dmg or tank sorc. Why not combine these things?
Gear
2x Intelligent Gaudius 2x9% res
1x Garb of Sumbras (5%+13% res)
1x CF kilt 12% res (13+19+12 res)
1x Cap All Stats/Cooldown
1x CF or Elite boots
1x Pendant 5 slots 3x intell lv6, lv3 or higher cloak and 3% res stone
But I guess most of you guys never lvled a sorc from lv 1 till 99. Quit changing chars is the answer ;-) I wasted over $1000 at chars that I deleted anywayz.
For the record, the maximum stats of a sorc can be (just a guess)
Over 80% skill block
Over 80% resistance
Over 80% elemental resistance
Over 15K hp
95% cast
78% cooldown
INCREDIBLE MOVEMENT SPEED, over 250% ;-)
With party buffs, bg buffs & cf foods ofcourse ;-)
