Ghom Crusader - Fire/DoT build to proc Furnace. No wrath generators or Akkhan, uses Aughild + Cain (improves attack speed, exp gained, toughness and elite dmg). Nice Cindercoat needed for resource costs.
Skills and passives:
Crusader - Game Guide - Diablo III
Gear:
Helm: Andariel's Visage (fire/str/attack speed or crit chance/red 41% exp gem)
Shoulders: Aughild (str/vit/all ressists/+% heavens fury dmg)
Chest: Cindercoat (fire/str/vit/3 str gems)
Neck: Fire/str/crit chance or attack speed/crit dmg
Gloves: Magefist (fire/str/attack speed/crit chance/crit dmg)
Bracers: Aughild (fire/str/vit/crit chance)

Ring 1: Stone of Jordan (fire/str/crit dmg/elite dmg)
Ring 2: Bul-Kathos's Wedding Band (str/crit chance/crit dmg/% life)
or Hellfire Ring (str/attack speed/crit chance/crit dmg)
or Ring of Royal Grandeur (str/attack speed/crit chance/crit dmg).
The first two provide higher DPS, but I recommend RoRG to avoid the games-per-hour limit and gain more EXP from the Cain 3-pc bonus.
Legs: Cain (str/vit/all ressists/2 str gems)
Boots: Cain (str/vit/all ressists/movement speed)
2H weapon: The Furnace
Shield: Lidless Wall (fire/str/attack speed/crit chance)
