The Core 1 is lacking. All you get is the core bonus which every core gives. I suggest that you move the Smite Evil feat and +1 Smite Evil charge to the core and leave the rest of the bonuses in Divine Smite. Maybe that's too much but something needs to go there.
For Consecration and Crusade please allow the healing and fire damage to also scale off of melee power if it's higher. This ED no longer has any spell casting bonuses so it seems backwards to make the Epic Strike and it's upgrades scale solely off spell power.
For the Crusade buff, does it refresh as long as you are standing within Consecration like it does in the live version or is 4 seconds it?
For Bring Down the Wrath, I suggest making it a multiselector with Blessed Strikes and replace Blessed Strikes with something else.
