It's a good start, but if you just want pure pve dps, then you'll want to change a few things:
1) Take the points out of electric bindings and backlash; these are only really useful in pvp (If you want to pvp, keep them).
2) Two of those points should go into exsanguinate, which increases the duration of affliction. The other two could go into the static barrier buff, or one in the static barrier buff and one in the casting distance increaser. Personally, I would put the two in the static barrier thing but also take a point out of electric induction to put in the distance talent.
3) The build you made it only at level 48, so once you get to 50 the other two points should go in disintegration in the madness tree.
