This definitely is NOT the norm of how to deal with packs of mobs.

WAR's overpower is the best way for consistent AOE damage and it comes with bonus Enmity. DRK has less damage before Lv56 with Unleash, but jumps into the same bit as WAR with Abyssal Drain. Paladins, much to my disgust, are indeed the root of the issue - out-of-the-running-mill Paladins often believe that no damage = bad and cannot possibly cause enough Enmity alone and therefore use enmity combos, Circle of Scorn and Total Eclipse primarily on trash packs.

If anything, a bad wave of Paladin players, but definitely not the norm. 2-3x Flash into FoF + Total Eclipse spam is the way to go. If using Flash in Shield Oath 3-4x, you can technically go into Sword Oath after that (with a Rampart at least...) and do your AOE combo in the DPS stance.
