WAR will always win the Battle of enmity solely because of all the skill that literally triples their damage. Even if you use all strength accessories WAR can rip the enmity right off you (will be a little harder if you do go all strength accessories lol). Regardless of WAR you should be miles ahead of all the other class minus the WHM if everyone has ilvl110 gear and ilvl115 weapons. I think you should sub out some of your VIT accessories and start using Melee accessories. Specifically ones that has Crit and Determination as secondary stats (if you don't need the accuracy).

PAL has gets 20% damage reduction by shield oath and damage reduction is better than increased defense or health.
