It doesn't take long at all to cap CE. Granted, you lose hate, it should be back on you by your next melee round or once the person who took hate gets hit once or twice. Not to mention that salvage was mostly /nin. /war offers provoke for some quick VE, if ever needed.
On big NMs, and there are few, but lets say Apademak, how viable is /war for a mnk?
Adjaza or w\e? Or even Dragua?

Even with Refresh atmas on your whms, /war is suicide and will require shadows on any tank.
Also on bigger things, hate is easier to lose and harder to cap CE where the mobs defense is so high.
Paladin is a better tank in this case.
