Don't really have a detailed build, but probally the most important one is 6 shield.
Damn, that's good. Once i was just running on a plain shield, while seeing archers infront of me. I raised my shield. What i didn't know, is that there was a cav behind me. When it attacked, it my shield. From behind. Derp.
Also, if they keep blocking your attack, thats good. I always just hold RMB and walk backwards to my allies. My shield will hold that unless there's a axe.
War spear is what i use.
