The power choice looks good. I believe the order of the powers in your build doesn't reflect the real situation. Mainly, you probably don't want to pick your status protection toggle at level 38. You can consider replacing resurgence by some other powers, for example ball lightning. You can shift some slots elsewhere to ball lightning, for example by cutting a slot from the passives and indomitable will.
The slotting can use some minor improvements. I would replace the doctored wounds in fast healing and health by some other IO sets with better bonus. I'm not sure if the two purples in knockout blow are really necessary. I think you can replace them with some other IOs. It seems like you're grabbing some heal bonus by 4-slotting Numina into high pain tolerance and rise to the challenge. I'm not sure how the heal bonus work. I believe the heal bonus is not the same as regeneration bonus. Maybe you're not getting what you want from the 4th Numina IO. I think you can move the 2nd slot from combat jumping to electrifying fences, then you can have the recharge bonus.
Here is my build for my SS/WP brute. I posted it else where but got no replies so i figured i would try its own thread. Thanks in advance for any help you may provide.
