Depends on what you plan on doing for your strategy. Pure FoHers blow, if you plan on charging or doing a hybrid paladin or anything then use a Heavens light if not then keep with a cheap item like Blessed. Either way both arent a good choice for a FoHer, you scarificing to many aspects for damage which isnt smart.
The problem is, that you'll need Attack Rating / ED% gear to enhance your Zeal, and it's blockable. You're basically dealing less average damage than a V/T, even if you JUST count the 75% block rate of an opponent...
