I wish you're guide would get some replies, I have been looking for a good one to follow; but don't normally trust guides with out lots of good replys. 
Looks good to me though.
It does have over 8000 views though...
Well I've been looking to try a different Blaster setup and this looks interesting.
I just wish Voltaic Sentinal would be like a controller pet, you only have to pull it up at the beginning ofa mission, but it has a horribly long recharge, hell I'd even take a 25 minute recharge, and the ability to dismiss it. I think that would help electrical blast A LOT.
I have an elec/elec/fire that is lvl 44 right now, close to 45. One thing that isn't updated in this guide is the use of IO sets now. I personally am not a big fan of discussing the "right" way to slot your character but I think that it is worth mentioning here for two reasons. First the old 3 dmg 2 acc can be better done now by using a Ranged Damage set. Secondly there are now sets for Endurance Modification which beef up Short Circuit and Power Sink.
I didn't like VS because it seemed to not be attacking where I was attacking and it didn't have the umph of say thouse cute little Fire Imps. I think that VS was an interesting idea for the set adding the Controller aspect to blasting, but I am just not a fan of how the little guy works.
So any blasters who have been playing since around i2 or so might remember my name, My old OLD guide is still up in the blaster guides section (or at least it was after this guide it may not be).
So heres the deal. The electrical blaster is a tricky one. Your attacks are a solid energy damage, which is nice for seeing your total damage (just one number) but that means energy resistant mobs (all 2 of them?) will cut your damage down. But face it unless your fighting a kheldian energy resistance isnt a huge deal. Other blasters have MUCH more resisted forms of damage.
So now onto the powers. Last time I wrote a guide people got on my case for not slotting -end into EVERY SINGLE POWER. something about me ignoring the secondary aspect of the power. Well now you will have some free slots, (good old 5damage 1acc just not worth it anymore)
So onto the powers.
Charged bolts
Cost:6
Activation:2

Recommended slotting:3 damage 2 acc (throw on 1 end drain or recharge if you want)
This is your first attack it is also the one you will use most often

Ball Lightning
Cost:17.5
Activation:1
Recharge:16
Range:80
Recommended slotting: 3 damage 2 acc, 1 recharge
This is your damage AoE, this is all you get besides Thunderous Blast (and short circuit).
Although its damage isnt stellar it has writhing which prevents enemies
from doing anything for a second or two.
Short Circuit
Cost:18
Activation:3
Recharge:20
Range:5 PbAoE
Special +20% natural ACC
Reccomended slotting 3 end drain 1-3 damage/acc mix and match
Short Circuit is the most misused and badmouthed power of the set.
However with 3 end drains in it you can drain a TON of end.
This is one of the jewels of the set. I cant be an AoE minion Killing machine
like Fire primary.But once you get SO enhances you can take down boss after boss taking no damage.
Aim
Cost:6
Activation:1
Recharge:90
Range:N/A
Recommended slotting 1-3 Rchrg redux maybe some tohit buff
Great power for fighting higher levels, things that dodge, etc. applications are limitless.

Range:150
Special 20% natural +ACC
Recommended slotting 3 damage+acc+rchg/enddrain
Zapp, This is your long range sniper blast. Its great its used primarily as an opener on your most dangerous enemy (stack damage on him early, keep the group busy with ball lightenings and such)
Tesla Cage
Cost:8
Activation:2
Recharge:10
Range:60
Recommended slotting N/A
Yey you get to your hold, In my first guide, I really didnt like this power, now I do, as an elec/ice blaster I can hold a boss (Stacked holds FTW) Elec lets you control your fights throughout in pve and this is great for keeping an extra lieutenant out of the fight for a while.
Voltaic Sentinal
Cost:30
Activation:3
Recharge:2 minutes
Range:60
Special: Natural +100% acc plus its a pet
Recommended slotting N/A
This is your pet. Slotted up it does ok extra damage. however this power is only useful VS
tough bosses or AV's other wise not worth it. It fires at random into groups you may not want to aggro.
If you take this unless you LOVE it do not slot it. its mostly a show power. This is my original stance on this power, It hasnt changed. I wish sparky acted like a photon seeker, or smart ball lightening :/
Thunderous Blast
Cost:11
Activation:4
Recharge:6 minutes
Range:60 Targeted AoE
Special: Natural +30% acc
Recommended slotting 3 damage 3 recharge redux
Ahh yes your nuke. This is the king of the elec powers. Like all nukes it leaves you drained.
however this power has RANGE allowing you to stay away while using it. AMAZING POWER Why no acc you ask? it has natural +acc, and you will pretty much only be using this after AIM/BU to get the most bang for your buck. I usually, AIM/BU, Ball Lightening SC, then Nuke if theres multiple liuets or a boss or something. I may be out of end, but so are they and I am the one with the Inspirations
That about sums it up. I am an electric/Ice blaster, (read: Blastroller) I do tons of damage to however dont be fooled. Just because you have holds and immobilizes, and slows doesnt mean your not a blaster :P
