Waste of time, IMO. The original intent of even having warforged was so people would be nudged towards 25 mans. Now that mythic has been scaled directly to a single fixed size, I think it's pointless. If they wanted to keep gear interesting while killing old bosses, they shouldn't have add portals and warps that make you skip half of them -- because no one will go back to something on farm just for a chance at warforged/socket/tertiary stats.
I say, ditch it.
