Might want to try a hybrid prot holy spec with shadowfang with lifesteal and another 1 handed with sader and swap back and forth. Arctic buckler, bubble bandage, stubs, pallys can be pretty decent for 19s
I liked spellpower on main 2h, for the versatility in support while maintaining that burst but I don't know if its ideal. maybe sader on smites for base physical damage then swap to glacial stone w/ fiery for that str buffed double proc action.
Edit: Seraph could work as some wild spirit stick counterpart to ur phat spellpower glacial stone smacks. shockadin life
