Looking for some help in building out my rad/martial blaster (slots and IOs) Debating between Mace or Leviathan mastery for patron powers. Was thinking about going Leviathan for Knockout Blow but not sure how much I lose in defense.
Current playstyle has been to use burst of speed with dragons tail and irradiate and then bounce out to for ranged damage and setting off atomic blast in my melee rotation for large mobs and EB/AV.
