vr4 sorcerer -help me maximize my build for pvp

Justiciar

Hey forums. I'm looking for advice on setting up my hotbar for PvP as a sorcerer. I've found my current build to be strong and fun to play with a high degree of surviveability but when going toe to toe with other veterans that have high health regen (especially dragon knights) I can struggle to burst them down fast enough. So I'm looking for something with high burst damage.

I am currently 22nd overall on the lower population campaign of goldbrand so this build has been decently successful for me

My current build - destruction staff sorcerer. 7 piece light armor.

1: mages fury - execute at 20 percent HP. I love this ability and with the passives from high elf and storm calling tree maxed out find it easy to finish off enemies when I get them low.

2: crystal fragments - strong cc with a high damage output. I will open with this and use repeatedly when the instant cast procs

3: crushing shock - I use this mostly for the cheap magicka cost instant cast to proc crystal fragments. The status effects seem useful but its been hard to gauge how effective the snare or reducing enemies damage from concussion has been.

4: hardened ward - my survivability spell. Repeatedly casting the 700 point shield has saved my life more times than u can count, can proc crystal fragments and due to passives increases health regen by 20 percent.

5: bolt escape - being able to quickly engage or disengage is useful. Also can proc crystal fragments.

Ult: soul assault.

My weapon swap is rarely used in PvP and is mostly an aoe DPs setup so I won't go into here.

But that's basically it. I like the build but am looking to increase burst damage to blow up single targets quickly. Any thoughts or input would be greatly appreciated.

I use Mages Wrath, Crystal Blast, Power Surge, Bolt Escape, Elemental Ring and either negate magic or soul assault. I also wear 7 piece light to get that 56% resist bypass on my targets. Bread and butter is mages wrath. For CC I dump crystal blast on targets, especially when hidden. Surge before you attack, lead with crystal, then follow up with mages wrath and light attacks. They'll hit the target all about the same time due to crystals travel time.

I've actually not used power surge since I don't find myself sing light attacks frequently at all. Do you find it worthwhile?

It only helps with weapon skill attacks. So it works with light/heavy attacks and any destro/healing staff abilities. In my case I use it for light/heavy and elemental ring (impulse) since that's a destro staff skill to up the damage.
