If anyone is interested in pushing DPS on Wizard, I've done many lives and solo R4+ on Wizard. Tiefling is an option but I like this DG setup better. Without strip Acid is by far the best element IMO.
Gear:
Dino (20/10/5 Acid,+2 Sacred,Walking)
Legendary Dusk Lenses
Dino (Voidscale,Voidfang,+5 Lightning,Resistance,Walking)
Legendary Kopru Bracers (+20 Force, Dread)
Bound Elemental Ring of Acid (Chained)
Bound Elemental Ring of Frost (Chained)
Osfield's Lightning Boots (Dread)
Dino Artifact (Int +15, 10/5 Force,Ghostly,Dread)
Legendary Walking Ancestor's Shroud (Walking)
Legendary Black Satin Waist
Epic Gem of Many Facets (Void Lore,Lore,Ins. Intelligence,Elders)
Elder's Focus (Elders)
Attuned Dino Weapon (Shadowscale, Meltfang, Brightclaw, Flamehorn, Dread)
Legendary Powder-Packed Barrel (Dread)
This packs in Walking, Dread, Chained elements, and Elders.
With this setup you can get standing ~900-1000 spell power across all elements pre-meta.
The critical chance is going to be around 50-65% depending on the elements but you cover Acid, Lightning, Sonic, Cold, Fire, Force, Fire, Void
The biggest downside is critical damage, the range is 40-100, but you can only really choose 2 to really push. Acid is the main one, the other chosen here is Force. That can vary on preference. Acid/Force can get up to 80-100 range, the other elements are going to be around 40-50. You can also go Acid/Fire.

Enhancements (98)
Archmage 41

Epic Destiny DC (75)
Draconic 35
Primal 26
Exalted Angel 14
I would only go Draconic if you take Ruin feats, otherwise I like Fatesinger as the main tree.

All in all it is possible to get what I would consider solid spell DPS from a Wizard, but it takes very careful gear planning and a lot of work compared to a single element caster!
