Heh, for some reason that build shows "Adrenalin Boost" at lvl 44. I've also noticed Ston3y's update has problems on /Elec armor regarding Energize so I guess we'll have to wait until he fixes it to see your proper build.
First, there's the guide in my signature for more explanations 
Now for the build itself, i would say the resulting stats are not bad at all, however i disagree on some power picks and the overall orientation of the build.
About the epics, i always hated focused accuracy, i think it's plain useless and even more with follow-up anyway. Physical perfection is nice, however that's not something needed i think. I'm doing fine with my claws/dark on live without it, and with cloak of fear instead of OG. So it's icing on the cake, i'm not sure i would go for that. Conserve power is more than enough.
Do you plan to run CoD all the time ? The defense you get with everything on is not bad at all while maintaining decent +recharge, i'm just not sure if it's worth all that much. I tend to aim for defense only when i can reach 40+ %, otherwise it will most likely last for the first 3sec of the fight then the debuffs will stack and your defense will vanish into nothingness. But of course it depends on what ennemies you like to fight. Anyway i would trade the end reduction IOs for two Lotg uniques in CoD and combat jumping.
I would move the slotting from Spin to Death shroud while removing the last IO and put an end redux instead, then put the purple set in Spin... The purple proc in there is awesome since it's a very fast recharging attack.
No shockwave ? It's a matter of playstyle but i would happily trade all the +defense in there for shockwave 
Anyway i'd say remove focused accuracy, put conserve power instead of PP, and add shockwave with the 6 slots from FA. I think you're going a bit overboard with endurance unless you plan to fight a lot of end draining mobs or solo AV with no insps.
Finally there's the KB protection. With only one IO for that it won't be enough, i advice adding a second one, and even a third one if you want to forget about KB. I used to have 2 of them and fake nems or some energy users still could knock me, with 3 i have yet to see anything going through the protection Combat jumping is a perfect IO mule for that: the karma -KB, the lotg unique, then a kismet unique.
Dark armor lover.
The Claws/DA Scrapper guide.
I liked my Claws/DA but I stopped playing her before because I never really had any clear direction for her. This is evidenced by her last few powers being Caltrops and unslotted Shockwave among other things. Either way, I've decided I want to put together a build for her to work toward. I've hit a bit of a snag, though and am wondering if it'd be better to take away some of my Recharge focus and put it towards Melee defense. Secondly, I'm wondering if I should just get rid of Super Jump and pick up Conserve Power instead. I can handle just using CJ+Hurdle but I wanted to get the opinions of others.
Here is the build, it requires ston3y's unofficial I16 Mid's update.
