Half Prot/Half Ret PvP/Leveling Build?

Hey, everyone. I was wondering if it would be possible to build a decent half-prot/half-ret pvp/leveling build. Something with good survivability that uses sword-and-board. Here's a preliminary build...

I figured this would give me a good crit rate and if I stack enough stamina gear it would push my spell damage high and give me some amazing crits.

What do you think? Any suggestions would be much appreciated.

I would go with this build instead. Maxamizes dps. Skipping Hotr, reckoning, and combat expertise is a large lose of dps.

If we wanted Ret to be a joke, we would have just left the tree as it was, and maybe kicked it a little for good measure. -GC
