Today I picked up a few new pieces, and realized that with only minimal reforging (and some un-forging) I was able to achieve my desired stats for hit/exp as well as parry/dodge ratio. Then I realized that there's a stat loss with any reforging and if you reforge every piece of gear, the total stats is decreased.
So in theory, if you kept reforging to a minimum and built your gear around pieces with the most desireable stats that did not need reforging, you would technically be better than someone with an identical ilvl and had every gear reforged.
If you're someone that's going for min/maxing... it seems not using reforging would be the way to go.
