So today i farmed some dungeons and nemezis on my 1st char, i transmutted set pieces and i have 4 pieces of that Sentinel of the Three set instead of desired stoneguard 
I was aiming to play my oathkeeper as phys retal warlord but i guess destiny got other plans for me, anyone tried that?
Sentinel has that nice synergy between bloody pox transmute, retal and new set but i have no idea if without soldier mastery its gonna be tanky enough for high end crucible farming and endgame bosses, whole dot spreading concept also looks cool like dk from wow.
And yes i saw builds in theorycrafting but no idea about they viability.
