Edit your post and add in there your setup. What gear and skills you use. We can then see if anything can be improved.

You have a nice choice of gear, so i think were good there. Just not sure where your stats sit. Magic sorcs rely on shields for defense, max magica means bigger shields and more damage. Spell damage i sit between 2300unbuffed - 3500 buffed, though im not sure where you want to sit so i enchant my destro and jewelry with spell damage.

Youll want divines trait, large pieces with infused. Enchanted with all magica, spell damage on the will jewelry, all attributes into magica.

Change tbs with spinner or at least julianos (divines only) (tbs WAS good only in high agressive warhorn active environment)
Try to get elegance jewelry with sharpened weapons (fire staff + 2x one handed)(any sharpened fire staff is ok (cp 160)

Basic sorc bar:
Bar 1: Force pulse///Crystal fragments///Bound aegis///Wall of fire///Inner light Ulti: Fire rage
Bar 2: Hardened ward///Liquid lightning///Bound aegis///Power surge///Thundering presence Ulti: Energy overload
Overload bar: Same as bar 2 just replace thundering presence with inner light

Execution: place dots under static mobs or kite them smart, so they stand in your ground based dots at least most of the time. Boss fights go the same way but u start with wall of elements->liquid->overload (untill boss dies or if it has many adds stop at ~220 ulti and pop destro ultimate)

I hope it will help
