As Lohkay said, Near will answer this when he has the chance. Anyway, I agree, you do want to
shoot for the soft cap of both those stats, but I've found through personal experience that it's not entirely
necessary to be capped. Granted you'll sit there swearing under your breath when have to spam your abilities a couple times to get them to hit, but I was told my other stats would make up where I lacked in hit/expertise, and for a long while I was still able to pull off top DPS (or in the top 3) on my Rogue being under-capped. I had 3 expertise on my Rogue from ToC up through midway in ICC.

Hurt my DPS a little, but it didn't make enough of a difference to really make a significant difference.
Looking at both of your profiles, there's not much different in your builds, other than Near going with Improved Leader and taking points out of Improved Mangle, and you taking Feral Charge. So there's nothing you're missing out on that he has. I recall Near mentioning his hit rating being low, which is partly due to the itemization of his gear pieces.
