Depends on the content. In Normal mode crap war should always MT. Savage Have the tank thats not a war tank(most of the time). In NM War pull with unchained. Once Unchained ends swap to dps stance and tank in it. As 0 of the current NM fights need tank stance and war can get most aggro while doing most damage.

If you are running with PLD DRK it depends on fight.
