In I7 I will be taking Strike, Slash and Focus as my main attacks on my claws/regen, with Eviscerate in there when Hasten is down and Shockwave when it's up. Looking at your build, I'm not sure how you will get a decent attack chain without any recharges in your attacks.
There's not much point putting defence buffs into Stealth as it's got such a poor base defence buff. Put the slots into MoG: 1xDamres, 2/3xDefBuff, 3/2xRecharge.
Whatever you choose, test it out on the Test server first to make sure it all works right.
Buoild look good, however i agree with kitty for the MOG and id put 3 dam 2 accuracy on you attacks to get full affect and hasten is great to have running when you pop instant healing, this will increase the healing rate of the power.
a better pick from the flight pool would be air sup, an excellent addition to your attack chain 
and i would use that over spin, any chance i get
You may want to consider swapping TP foe and TP for hasten and SS. Hasten lets reconstruction, dull pain and IH cycle faster which helps to keep you alive, plus your big attacks cycle faster increasing your damage output. Also SS won't need any slotting, giving you a couple more to play with.
just wanted to say thanks for all your suggestions. it has given me food for thought.
Is there any reason why you didn't get Follow Up, I'm curious?
@Unthing ... Mostly on Union.
Get Follow Up !!
You´ll need the damage buff especially in PvP !!
I need help with my scrapper who is lvl 44. With the improved changes to claws and the fact i messed my last respec up. I have been playing about with ideas on how to spec.In current my build i have taken:
claws: strike(not used), FU, focus, evis and shockwave. regen: FH, recon, QR, DP, integration, resilience and IH. flight: Air Sup and flight.
fighting pool: kick(not used), tough and weave.
leadership:assault and tactics.
body master: CP and LBE
I wanted to try something different and it has not worked out to well. I have come up with this build and want to know what people think.

I might change the travel side of the build change TF and teleport, with hover and flight. I have never used MoG before so i am not sure about this, i did think about getting hasten to get IH back quicker. I took Dark Mast to have a litte crowd control. Thanks for any ideas and suggestions.
