Warr in this case is the natural fit for MT, for the reasons mostly already mentioned:
- WAR Inner Beast every death sentence
- PLD can stoneskin from the OT position
- PLD does better job stunning Dreadguards during that phase - OT better position for that

However, PLD works OK too. My static goes purely PLD MT & WAR OT just because PLD learned it, knows it cold, and so why bother learning new positions.
