Use Homo for elemental battles for the resists....use homo for melee battles for the block...so when are you actually using D-F then Sov? Just PnB NvN?
I personally wanted to make a new necro that uses D-F to help reach 125 FCR and the extra pnb skills are good too but....it seems like its only good in NvN then and even then when its not a summoner...Perhaps this is why Soulesschild believes in homo over df and why I personally have never used it in the past myself.
