The challenge is simple: Use only skills, runes, and passives that are level 25 or lower to create a build that you will use to finish a normal run through. Post your build, and a short explanation of your reasoning (no essays please). Make sure to include fun details like "Playing this barb with my wife's DH" or "Solo rushing normal" etc etc. Oh god, I'm bored.
This is what I'll run on Bnet public games after my first run through with my better half. Builds around the Berserker Rage passive you get at level 20. Only fury spenders are Battle Rage for damage, and Earthquake for the sake of having it. Leap is for fast progression between monster packs, Pound of Flesh is so I never have to stop.
