Gladiator Block/Lacerate Build Need Help

Doing a Gladiator 1hand/shield build and was looking for some help to improve it. With all the new nodes, I was wondering if my build was optimal or if there are some tweaks that will result in more damage.

Also, I have a free Ring or Helm slot (where I don't need to cover resistance) and was wondering if anyone has any suggestions there. Do I take a Starkonja's and replace my Romiro ring with a regular ring or do I replace the Romiro with a Hungry Loop maybe?

Heres a link to my character:

Something like that?
