OK guys, I need some help with putting together a mag sorc build for pve. everyone is telling me necro is the way to go but then I hear from guild mates and others on the forums that pets aren't always good in trials and can sometimes be a burden. I'm not opposed to running pets personally, if its the best way to go then its the best way to go but I don't wanna be a burden to anyone I'm in a trial with. I don't PVE much so I'm not on the up and up for whats good and whats bad, I also haven't done halls of fabrication yet. I would like this toon to be good for all PVE content, VMA, DSA, and all trials.

What I'm working with-
Altmer mag sorc 630 cp

Precise masters lightning
precise masters inferno (already golded, I only have maelstrom ice staff nirnhoned. with HotR DLC coming soon precise looks like a potential BiS so id like to work with these)

Illambris heavy helm infused
illambris light shoulders divines

Full Divines BSW Golded

Gold infal jewelry (got 2 gold moondancer, haven't got 3rd yet)

I'm not opposed to farming new gear. I want to melt ***.

**MAIN INDECISIONS**
Wall of flame or wall of shock? I know 75 into ritual gives offbalance with in turn gives 10% additional damage for shock, but flame does more base damage and gives me a fire AoE to increase flame illambris procs. Ive heard both are good.

Use 2 pets? only volatile? or none?

Do Daedric mines have any place in PVE? ive seen some people use them to artificially increase DPS tests but in actual application are they any good?

Feed back is appreciated.
