I just took a look at your ele's. Silverlion, silvercow & silverbacked.

I'd recommend to
- change glyphs: totem of wratch, lightning bolt and either flame shock / lava
- update a few gems/enchants
- on silvercow you should use the tailoring cloack enchant rather than the haste enchant (lightweave embroidery)

Depending on your rotation i'd say that 4-5k dps is acceptable with your gear.
